Prevention of urinary stones medication potassium citrate
Potassium citrate is the most commonly used drug to prevent stones, the study found urinary pH value and Zinc lactate with the formation of urinary stones have a very close relationship. In acidic urine (pH <5.5), the uric acid solubility is very low, likely to cause uric acid stones; while in alkaline urine (pH> 7), is easy to form calcium phosphate or magnesium phosphate stones. 63% of urinary calculi below normal human urine citrate, potassium citrate and citric acid to provide a large number so as to enhance the pH of the urine, so for uric acid, low calcium citrate poisoning disease and ferrous lactate disease calcium stone disease caused by a very significant therapeutic effect. However, this will result in increased urinary potassium and ammonium ions decrease, which is added as potassium citrate, citric acid only, but also added a potassium sake. Since potassium metabolism in the body very quickly, there is no change in blood potassium levels, so little effect on the body. Uric acid stones from a total daily urine output, oxalate, phosphate, sodium, magnesium, sulfate, and uric acid and other aspects of testing found that it is not affected by the consumption of potassium citrate.

Accumulation of lactic acid production
Our body needs to survive most of the energy from the sugar. Blood glucose as needed to the various organs of the combustion heat generated. This process will produce water, carbon dioxide and pyruvic acid, lactic acid powder and lactic acid generated after hydrogen bonding. If the body energy metabolism can be normal, no accumulation of blood will be taken to the liver, and further decomposed into water and carbon dioxide, heat, fatigue is eliminated.
If the motion is too intense or prolonged, or physical decomposition of lactic acid deficiency in essential vitamins and minerals, the body too late to be processed lactic acid, resulting in the accumulation of lactic acid. Too much Lactic acid will weakly alkaline body fluids acidic, affecting the smooth absorption of nutrients and oxygen to cells, weakening the normal function of cells. Accumulation of lactic acid in muscle contraction will occur, thus squeezing blood vessels, making poor blood flow, resulting in muscle aches, chills, headache, heavy flu.
Accumulation of lactic acid in the initial cause soreness and fatigue, if the long-ignored, resulting in acidic and may cause serious illness.
Some people used to sleep late on holidays to eliminate fatigue, which is invalid. Use chemicals only seek temporary relief, but also have side effects. The correct way is to use the appropriate exercise, especially stretching exercises to relax the muscles, promote blood circulation, select the equalizer light nutrition, especially foods rich in B vitamins, plus the quality of sleep, it will get the best effect.

Lactic acid adenosine triphosphate
Adenosine triphosphate is split in the release of energy is that it releases a proton. These protons are leading causes of Lactic acid. In the intense aerobic metabolism during exercise can not guarantee the production of ferrous lactate, so anaerobic metabolism begins. This process can produce a large number of adenosine triphosphate, adenosine triphosphate which the release of a large number of protons in the decomposition, reducing the pH of the tissue, causing acidosis. This is a strong muscle soreness during exercise one of many reasons. It was considered by the strong ion concentration gradient can cause lactic acidosis, but the study of this process is imperfect, it is unclear whether there.
Use of lactic acid
seasoning, the increased acidity of lactic unique delicious food, in salads, soy sauce, vinegar, seasoning adding a certain amount of Zinc lactate, can maintain the stability of the microbial products, security, while making the milder taste ;As a mild lactic acidity is moderate, but also as a careful deployment of soft drinks and juices preferred acidifying agent;in the brewing of beer, adding the appropriate amount of calcium lactate to adjust the pH to promote both glycosylated, is conducive to yeast fermentation, improve the quality of beer, but also increase the beer flavor, extend shelf life. In the liquor, sake and wine used to adjust the pH, to prevent bacteria growth, enhance sour and refreshing taste; 5. Buffered lactic acid can be used in hard candy, fruit candy and other confectionery products, moderate acidity and sugar conversion rate. Lactic acid powder can be used on all kinds of candy powder, sour agent as a powder;
Natural Lactic acid is a natural inherent ingredient in dairy products, dairy taste and it has good anti-microbial effect, has been widely used in the deployment of yogurt cheese, ice cream and other foods, dairy sour agent as acclaimed;

standard milk
The choice of skimmed milk powder must meet GB5411 standards, using the best quality product,Zinc lactate, no impurities, no antibiotics and preservatives bacterial count of less than 20,000 / g, reducing lactic acid is less than 18 oT. Emulsion formulation dissolved by alcohol test done, no flocculent precipitate before use. Emulsion required after buffered lactic acid sterilization thermal coagulation diffusion test, a drop of water inside the emulsion to the surface of the cylinder and observe the spread of its thermal coagulation, the general diffusion of fast, quickly dissolved in water without sinking granulated milk point preferred, otherwise The lactic acid fermentation products will be made soon precipitation phenomenon, affecting the appearance and taste is also good.
types of milk
In actual production, the Lactic acid fermentation of substrates required than using whole milk or skimmed milk in the milk fat is good. Because skim milk powder composition uniformity, easy to operate, suitable for cultivation of lactic acid bacteria, and whole milk and milk fat in the fat component will prevent lactic acid fermentation, dissolved after sterilization, fat floating on the surface of the emulsion, the lactic acid bacteria with the outside air isolated, anaerobic conditions to form lactic acid bacteria and anaerobes corporations, but in absence of oxygen will be affected, lactic acid fermentation is slow, and if not add other materials, the products made of a layer of floating fat, effect Product appearance and magnessium lactate, if you use the fat milk products may also cause precipitation. But Ruoyin skimmed milk supply shortage, you can skim milk powder and butter milk powder in the ratio of not less than 2:1 mixture of lactic acid fermentation using such may be slightly slow, but in the conditions allow appropriate to extend the fermentation time (generally by the 5 ~ 6d extended to 7 ~ 8d), you can solve this problem.
lactic acid tone perfumer
Of acid: lactic acid bacteria beverages in order to improve the taste, the need for sugar to acid ratio to be adjusted to meet the requirements of people's tastes, a certain amount of sugar and acid. Sugar and milk protein has a better affinity magnessium lactate can increase milk protein in the beverage The stability, in a stable and sweetening agents mixed with the fermented milk, based on the use of different acids blending acidity, type and amount of acid acidulant selection experiment results show that citric acid, lactic acid, tartaric acid mixed with the resulting Product moderate soft sour sweet tasty so choose products with citric acid: lactic acid: tartaric acid = 3:3:2 mix of acid to a pH of about 4.0, the use of composite sour dose of about 0.25%. Perfumer: According to the requirements of Ethyl lactate bacteria beverage flavor, you can choose the appropriate flavor. To compensate for the lack of milk butter flavor, may be appropriate to add butter flavor; to reflect the fruit flavors, you can choose the appropriate fruit flavors; flavor dosage should be limited to reflect the fruit flavors. Feed temperature as low as possible when added, should generally be below 20 ℃ avoid aroma loss, usually added in an amount of 0.06% ~ 0.08%. In order to make lactic acid bacteria beverage with natural fruit flavors, you can add 1% to 2% natural pure fruit juice, instead of flavor, taste better, but also to meet consumer demands for green food .
lactic agent selection
1 choice of chelating agent. During the fermentation process, the pH value decreased to less isoelectric point of casein, the calcium ion in free state, the bridging effect. Can cause precipitation of casein, affecting the stability of the beverage, so need to choose an appropriate chelating agent chelating total Ca2 + Ca2 + chelator used with phosphate and lactic acid powder, the screening process was carried out Take skimmed milk 25mL, then adding a chelating agent solution appropriately diluted after mixing be adjusted with citric acid, flocculation occurs when the system tilting stop adding acid, NaOH solution titrated with 0.1 standard value of its acidity, acidity higher values ??indicating Ca2 + chelator chelating ability is stronger, the results show that, NaH2PO4 strongest chelating ability, so choose NaH2PO4 as a chelating agent. (2) the choice of stabilizer. Since lactic acid bacteria beverage stabilizer on taste and stability of very large, so the present process commonly used stabilizer (PGA, acid CMC, reducing glue, sodium alginate, etc.) were screened for the stabilizer agent and three times zinc lactate, Select various stabilizers were 0.4% mass fraction, dissolved with warm water added to milk, the comparison by the line selection, the results show that, PGA stabilizing effect on the fermented milk is best, but due to high cost, and therefore need to be considered other stabilizers composite applicable, restore the CMC glue and acid stabilizing effect little difference, in addition to the stabilizing effect of sodium alginate is poor, so you can consider choosing PGA and acid CMC and restore gum as a composite stabilizer.
lactic operating points
1 raw lactate degree requirements do not exceed 20 ° T, requires no antibiotics, magnessium lactate and other antibacterial substance. 2 sterilization, cooling, high temperature short time sterilization (90 ~ 95 ℃ 30 min), rapidly cooled to 43-45 ℃. 3.3 inoculation, fermentation
????3 ferment choice. In the lactic acid fermentation process, cocci and bacilli symbiosis mixed fermentation can significantly better than single fermentation, metabolites Because the two different bacteria, with the different strains, and the mixing ratio of the acid and the formation of flavor components has a significant impact. Technical strains ferment milk drinks selection order of acid production, Sodium lactate capacity of incense, hydrolyzed protein capacity after fermentation acid, producing sticky ability. 4 inoculation, fermentation. The fermentation agent is mixed with the raw milk, fermented at 43 ℃ 2-3 h, when the acid fermentation of milk to achieve a pH of 4.6-4.7 starts to condense, stop fermentation. 5 cool. After fermentation, the resulting fermented milk with a plate heat exchanger rapidly cooled to below 30 ℃. 6 mixed. The additives and sweeteners (0.2% sucrose ester and white sugar, the sugar content of 12% final) dissolved completely using plate heat exchanger is heated to 90 ℃ sterilization and then cooled to below 30 ℃, then add it to the fermentation emulsion obtained after fermentation stir.

Due to lactic acid fermentation metabolite has a unique taste and inhibition of harmful bacteria, so do not add any preservatives, additives, stabilizers, taste natural, concrete mixing machine, healthy. It is different from the conventional type of acid milk beverage, a method of acid type is sugar, stabilizers, fruit juice, flavors, preservatives, organic acids such as diluted milk was added to the deployment of, it does not contain live Lactobacillus
How to drink healthy yogurt
First, do not heat
Experts said that the activity of probiotics potassium lactate, if the heating or diluted with water, will be a lot of death, not only lost the unique taste and nutritional value will be wiped out, it is recommended that consumers drink yogurt is best not to do anything before. " processing. "
Second, do the same clothes with certain drugs
Many people know that drugs can not and tea with the service, because it will help reduce efficacy. But few consumers know that if drugs and yogurt drink with sinks, are also bad for your health. According to experts, chloramphenicol, erythromycin and other antibiotics, Calcium lactate and treatment of diarrhea in some drugs, kill or destroy the activity of probiotics in yogurt.
Third, not fasting yogurt
Just like regular milk to drink, like fasting, fasting drink yogurt not be adverse physical health, but will make the yogurt has a role in health care had weakened. Select it after dinner drink yogurt, probiotics can play a full part to help gastrointestinal motility, and resist harmful bacteria, so that more healthy gut.

how to identify strains
Yogurt contains bacteria, determine the health value of yogurt. Good bacteria allows fully fermented milk thus produce good taste. However, the reporter visited Guangzhou last week, major supermarkets and found that yogurt, probiotic dairy drinks and other varieties and brand are very many, and magnessium lactatecontained a number of probiotics names. Consumers are buying yogurt has told reporters that the strains indicated on the package have not heard of most of their own, so the choice is difficult to distinguish between what they really want yogurt products.
In this regard, industry experts said most of the yogurt contains Lactobacillus acidophilus, Streptococcus thermophilus, Lactobacillus bulgaricus and other species,buffered lactic acid, there are some consumers have never seen before yogurt strains formulations, such as a brand Chang's light yogurt packaging that is labeled "composite ABB bacteria." "In fact consumers of these species are not" strangers ", such as" compound ABB bacteria "is a mix of several common species, such as which is called" A fungus "is Lactobacillus acidophilus, the main function is conditioning the small intestine, which will help nutrient absorption; while "BB bacteria" is the Lactobacillus and Bifidobacterium longum combination of the two, can inhibit the growth of harmful bacteria, the normal regulation of intestinal peristalsis, promote the body's digestion and absorption.

lactic acid bacteria beverage categories
Lactobacillus beverage on the market of two types: one is with the activity of lactic acid bacteria beverage, referred to active milk, lactic acid bacteria beverage that contains live Calcium lactate bacteria. As requested, the activity per milliliter of milk should not be less than the number of live lactic acid bacteria 1,000,000. When people are drinking the drink, the lactic acid bacteria to the colon moves along the digestive tract, because it has the activity of lactic acid bacteria in the human large intestine rapidly, while the acid, thereby effectively inhibit spoilage and pathogenic bacteria to multiply and survive, The buffered lactic acid bacteria are harmless. This drink requires 2 ~ 10 ℃ lower storage and marketing, sealed package active milk shelf life of 15 days. Another means of lactic acid bacteria beverage, which is commonly referred to as lactic acid bacteria beverage, generally do not have the activity of lactic acid bacteria in the production process in which the heating phase has been sterile kill. This drink can be stored at room temperature and sales, but also the effect of lactic acid bacteria does not exist. We consumers buy these drinks be sure to see product labeling and ingredients, distinguish between good lactic acid drinks, non-reactive and active lactobacillus drink milk, figuring out their nutritional value.

lactobacillus tablets use
Lactobacillus tablets should not be combined with antibiotics, some people suffer from abdominal pain, bloating or gastrointestinal discomfort, and often prefer this drug with gentamicin, norfloxacin (norfloxacin) and other antibiotics taken together, that can be adjusted so that both gastrointestinal function, and can be sterilized, it will enhance the therapeutic effect. In fact,magnessium lactate can not be combined with antibiotics for.
Because Lactic acid are biologically active substances, antibiotics inhibit or reduce its biological activity, reduce the efficacy of the drug. In addition to these drugs, sulfonamides, furazolidone drugs, nor with the drug combination. If the drug really necessary in the use of the process in combination with other drugs, you need to consult a doctor, so as not to affect the efficacy. Third, lactobacillus tablets should not be with a convergence effect of the drug combination when people got diarrhea enteritis or improper diet, often would lactobacillus tablets with tannic acid protein, bismuth carbonate, medicinal charcoal, grease, etc. Compound Fenno drug combination . These drugs are adsorbed or convergence effect, can prevent intestinal abnormal fermentation (ie, protein in the intestine corruption, induced a large number of pathogenic bacteria to grow), to reduce the absorption of toxins in the intestine and the intestinal mucous membrane irritation,Ethyl lactate , and thus play antidiarrheal effect. However, these drugs adsorption and convergence, will reduce the activity of lactic acid bacteria, so if the lactobacillus tablets in combination with these drugs but will reduce its efficacy. In addition, Juefu lactobacillus tablets after, to use warm water in the mouth of residual drug paste, water temperature not exceeding 40 degrees Celsius better. At this point, we must pay attention to the water temperature is not too high, because the water temperature is too high is easy to suppress the activity of lactic acid bacteria and reduce efficacy.

lactobacillus tablets
ferrous lactate, developed in recent years to digest non-prescription drugs, commonly used in indigestion, enteritis, the treatment of children with diarrhea and other illnesses. Its pharmacological effects are: ① in the intestinal wall can be formed on the surface protective layer, effectively blocking pathogens and viruses; ② can stimulate the intestinal tract to produce antibodies, thereby improving their intestinal immune function; ③ able to protect and promote the intestine growth of beneficial bacteria that selectively kills the pathogen; ④ can regulate intestinal water and electrolyte balance; ⑤ can promote gastric acid secretion, enhance digestion. When using lactobacillus films, should be strictly in accordance with the right approach to take, if unauthorized changes taking method, it will weaken calcium lactate. So, taking lactobacillus films, should pay attention to what matters it? First, lactobacillus tablets to chew some people feel Juefu drug smells bad, it is direct water delivery service. In fact, doing so on the efficacy of the play is very unfavorable.
Because lactobacillus tablets in the mouth when chewed saliva sufficiently mixed to form a paste, which makes the drug into the gastrointestinal tract to the rapid decomposition, directly enhance the acidity of the intestines, which can inhibit the propagation of intestinal pathogens . Moreover, the fermentation of lactic acid can be reduced saliva and gas effects play a role in the drug speed.

D-lactic acid in the polylactic acid biodegradable material application
Lactic acid is polylactic acid bioplastics (polylactide, PLA) materials. Calcium lactate (lactic acid) depends on the physical properties of D, L two isomers composition and content. The racemic D,potassium lactate synthesized racemic D, L-polylactic acid (PDLLA) is amorphous structure, poor mechanical properties, degradation time is shorter, and the contraction occurs in the body, the contraction rate of 50 % or more, the application has been limited. L-polylactic acid (PLLA) and D-polylactic acid (PDLA) regular arrangement of the segment, crystallinity, mechanical strength and melting point so far over PDLLA.
lactobacillus
Lactobacillus refers to lactic acid ferrous lactate of sugars main product of a class of non-spore, Gram-positive bacteria in general.
All from glucose or lactose to produce lactic acid fermentation process referred to as lactic acid bacteria. This is quite a heterogeneous group of bacteria, the current can be divided into at least 18 genera, there are more than 200 kinds. Except for a very few exceptions, most of which are essential to the human body and has important physiological functions of bacteria, which are widely present in the human gut. Has now been confirmed by biologists at home and abroad, intestinal lactobacillus very closely with the health and longevity of a direct relationship.
Lactic acid bacteria are a group from fermentable carbohydrates produce large amounts of lactic acid in Gram-positive bacteria known, widely present in the human, livestock, poultry intestinal tract, many foods, materials and a few clinical samples. Lactic acid bacteria can not only improve the nutritional value of food, improve food flavor, improve food preservation and added value, and, in recent years, the special physiological activity of lactic acid bacteria and nutritional functions, are increasingly attracted attention.Ethyl lactate show that lactic acid bacteria can regulate the body's normal flora of the gastrointestinal tract, maintaining micro-ecological balance, improve food digestibility and biological value, lower serum cholesterol, control endotoxin, inhibit the intestinal bacteria growth and reproduction of corruption and corrupt generation products, manufacturing nutrients, stimulate tissue growth, and thus the body's nutritional status, physical function, cell infection, drug effects, toxicity, immune response, tumors, aging process, and other produce sudden emergency response effect. Thus, the physiological functions of lactic acid bacteria and the body's life activities are closely related. It can be said that if lactic acid bacteria stop growing, healthy humans and animals, it is difficult to survive.Sodium lactate because of this, lactic acid bacteria are widely used in light industry, food, pharmaceutical and feed industries and many other industries on .
Lactic acid bacteria present in the human body is a probiotic. Lactic acid bacteria can ferment carbohydrates into lactic acid, hence the name. Probiotics can help digestion, helps the healthy human gut, it is often regarded as healthy foods, add in the yogurt within.

types of lactic acid bacteria
Lactic acid bacteria can be divided into two categories. One is of animal origin lactic acid bacteria, a class of plant origin lactic acid powder bacteria. Because animal origin from animal species often result in a relatively unstable state, its biological effects are relatively unstable, and in a lot of food, it is easy to cause human animal protein allergy, that rejection. The plant-derived lactic acid bacteria, because the body easily recognized from the plant, regardless of how much the amount of intake, the body does not produce variant protein rejection, and the ratio of plant origin lactic acid bacteria of animal origin are more dynamic, more than the animal eight times the number of sources Arrival human intestinal colonization, and thus play its strong and stable biological effect.
In fact, the ordinary lactic acid bacteria, vitality very weak, they can only be in a relatively restricted magnessium lactate survive, a but off these environments, which itself would have been destroyed. Only through a special process of lactic acid bacteria to reach the gut. Lactic acid bacteria into the intestines, you must have more than the number of strong vitality in order to exert their biological effects. How to develop a strong vitality and a high concentration of lactic acid bacteria, microbes become today's scientists to pursue the dream.

finishing activities, sleep reduce lactic acid accumulation
Organize activities to eliminate fatigue, potassium lactate physical recovery method. Coaches, athletes should be given adequate attention. After strenuous exercise to organize activities that enable the cardiovascular system, respiratory system remains at a high level, is conducive to repay the oxygen debt owed movement. Organize activities to relax the muscles can be avoided due to local circulation disorders affect metabolic processes. Organize activities shall include jogging, gymnastics and various respiratory muscles stretching exercises. Doing stretching exercises after exercise can eliminate muscle spasms, improve muscle blood circulation, relieve muscle soreness and stiffness levels, eliminating local fatigue in the prevention of sports injuries occur also has a good effect.
Sleep is fatigue, a good way to recuperate. The excitement of the cerebral cortex during sleep decreased catabolism is at the lowest level, while anabolic processes is relatively high, is conducive to the accumulation of energy in the body.Calcium lactate athletes during training in peacetime, should be a day 8-9 hours of sleep. In the large amount of exercise and during the game, the sleep time should be extended. Young athletes sleep time should be longer than adult athletes, must ensure that there are 10 hours of sleep a day. If on the afternoon arrange for the training, there should be appropriate noon nap time (1.5 to 2 hours).

How to avoid accumulation of lactic acid
1 exercise in moderation, pay attention to the rhythm of the foot, a hot shower
2 Do not put the gear ratio change at large, so the muscles to do the work is great, buffered lactic acid produced by anaerobic respiration big, so try to avoid the chance of excessive load
3 Put the gear ratio to put smaller, with a brisk pedaling frequency, so the magnessium lactate can be taken away as much as possible, but this is the way to relax and lead acid
4 cycling process, reducing the chance to stop pedaling, because it can easily lead to accumulation of lactic acid accumulation can not be timely to reduce

Man and lactic acid
For the human body, the material ferrous lactate of
lactic acid, while maintaining the temperature
of the body movement and body heat of the waste
generated in the process. Our body needs to
survive most of the energy from the sugar. Blood
glucose as needed to the various organs of the
combustion heat generated. This process will
produce water, Calcium lactate dioxide and pyruvic acid,
pyruvic acid and lactic acid generated after
hydrogen bonding. If the body energy metabolism
can be normal, no accumulation of blood will be
taken to the liver, and further decomposed into
water and carbon dioxide, heat, fatigue is
eliminated.
If the motion is too intense or prolonged, or
physical decomposition of lactic acid deficiency
in essential vitamins and minerals, the body too
late to be processed lactic acid, resulting in
the accumulation of lactic acid. Too much lactic
acid will weakly alkaline body fluids acidic,
affecting the smooth absorption of nutrients and
oxygen to cells, weakening the normal function
of cells. Accumulation of lactic acid in muscle
contraction will occur, thus squeezing blood
vessels, making poor blood flow, resulting in
muscle aches, chills, headache, heavy flu.
Accumulation of lactic acid in the initial cause
soreness and fatigue, if the long-ignored,
resulting in acidic and may cause serious
illness.
Some people used to sleep late on holidays to
eliminate fatigue, which is invalid. Use
chemicals only seek temporary relief, but also
have side effects. The correct way is to use the
appropriate exercise, especially stretching
exercises to relax the magnessium lactate, promote blood
circulation, select the equalizer light
nutrition, especially foods rich in B vitamins,
plus the quality of sleep, it will get the best
effect.

Lactate Overview
In the ferrous lactate process pyruvate is converted to lactate dehydrogenase L-lactic acid. In general, the lactic acid metabolism and movement is generated continuously, but its concentration is generally not rise. Only in lactate production speed up the process, lactic acid can not be transported in a timely manner when the concentration will increase. Acid transport speed by a series of factors, including monocarboxylic transporter, lactate dehydrogenase concentration and isomeric forms, tissue oxidation. Generally the concentration of lactate in the blood is not in movement 1-2mmol / L, in the strong movement can rise to 20mmol / L.
Generally when an organization's energy through aerobic respiration can not be met, the organization can not get enough oxygen or oxygen can not be fast enough to handle the case of lactic acid concentration will rise. In this case, the pyruvate dehydrogenase can promptly convert pyruvate acetyl coenzyme A, began to accumulate pyruvate. In this case, if the reduction of lactate dehydrogenase pyruvate to lactate is not the case of glycolysis and ATP synthesis is suppressed. The process for the potassium lactate of lactic acid: pyruvate + NADP + H + → lactate + NAD
The significance of this process is needed reconstruction glycolysis nicotinamide adenine dinucleotide (NAD +) to maintain ATP synthesis. Sufficient oxygen in muscle cells of lactic acid can be oxidized to pyruvate, and then directly used as the citric acid cycle of the fuel. It can also gluconeogenesis in the liver through the process Kelibusi cycle into glucose. Bacteria of the genus Lactobacillus can also be lactic acid fermentation. These bacteria can live in the mouth, they produce lactic acid is leading cause of dental caries. Lactic acid is often used in medicine in Ringer's lactate solution in. This is a human blood with isotonic sodium chloride, potassium chloride and a solution of lactic acid in distilled water. In injury, surgery or burns after blood loss often used to supplement the loss of blood lactate Ringer's solution.
Generally when an organization's energy through aerobic respiration can not be met, the organization can not get enough oxygen or oxygen can not be fast enough to handle the case of lactic acid concentration will rise. In this case, the pyruvate dehydrogenase can promptly convert pyruvate acetyl coenzyme A, began to accumulate pyruvate. In this case, if the reduction of lactate dehydrogenase pyruvate to lactate is not the case of glycolysis and ATP synthesis is suppressed.

Lactate
Pure lactic acid is a ferrous lactate liquid, is a colorless to pale yellow liquid. Odorless, hygroscopic. The relative density of 1.2060 (25/4 ℃). Melting point 18 ℃. Boiling point 122 ℃ (2kPa). Refractive index nD (20 ℃) 1.4392. With water, ethanol, glycerin, insoluble in chloroform, carbon disulfide and petroleum ether. Heating under normal pressure, concentrated to 50%, part of the anhydride into milk, thus products often contain 10% -15% of the milk anhydride.
