Lactic acid is a carboxylic acid, the molecular formula is C3H6O3, containing a hydroxyl group, belonging to α-hydroxyory (AHA). In an aqueous solution, the carboxyl group releases a proton to generate lactate ion CH3CH (OH) COO-.

Generally speaking, when the energy of the arrangement cannot be satisfied with oxygen breathing, it is arranged that the oxygen that cannot be obtained may not satisfy the quick treatment of oxygen, the concentration of lactic acid will rise. In this case, the acetone dehydrogenase cannot be converted to acetyl coenzyme a, pyruvate start-up. In this case, if the lactate dehydrogenase does not reduce the reduction of pyruvic acid as lactic acid, the composition of triphosphate is inhibited.

The lactate dehydrogenase is converted to a left lactic acid during the fermentation process. Lactic acids are constantly occurring in general metabolism and motion, but its concentration generally does not rise. Only in the lactic acid occurs, lactic acid cannot be transported in time to increase. The lactic acid transport speed is affected by a series of factors, and includes a monocarboxy-dient, lactate dehydrogenase concentration and isomer form, and the oxidative capacity arranged.

The lactic acid transport speed is affected by a series of factors, and includes a monocarboxy-dient, lactate dehydrogenase concentration and isomer form, and the oxidative capacity arranged. Generally, the concentration of lactic acid in the blood is from 1-2 mmol / L during non-exercise, and can rise to 20 mmol / L during intense exercise.

Ricia oil contains a lot of ricic acid (more than 80%), so many unique properties:
1. It is easy to dissolve in ethanol, which is difficult to dissolve in petroleum ether. This feature is more likely to distinguish between castor oil from other grease.
2. The viscosity is much higher than that of the general oil, and 25 is 680 cps, the viscosity index 84, the friction coefficient is very low (0.1).
The fluidity of castor oil is good, and the refined castor oil can still flow in -22.

The melting point is 13.5°C, the boiling point is 140.9°C, and the density (20/4°C) is 1.0611g/cm3. The chemical nature is lively. It is easy to polymerize in air and can be reduced to propionic acid by hydrogenation. Addition with hydrogen chloride generates 2-chloropropionic acid. Used in the preparation of acrylic resins and other organic synthesis. It is made by oxidation of acrolein or hydrolysis of acrylonitrile, or made by carbon monoxide, acetylene and water under the action of nickel catalyst.

It uses oxygen with a purity of 93.5%-99.2% and combustible gas (such as acetylene) to produce a flame of extremely high temperature, thereby melting the metal. The metallurgical process cannot do without oxygen. In order to strengthen the production of nitric acid and sulfuric acid, oxygen is also required. Instead of using air, a mixture of oxygen and water vapor is blown into the coal gasifier to obtain coal gas with high calorific value.

The industrial neighborl xylene is a raw material, first washes the acid layer to the acid layer colorless, then use 10% sodium hydroxide solution, water is washed to pass, and the aqueous layer is separated, and the calcium chloride is borned with anhydrous carbon. After the distinction is low, the intermediate fraction is collected, that is, a pure product.

The classification of citric acid should be based on the number of crystal water contained, such as: anhydrous, monohydrate, and dihydrate. Anhydrous lemons can be obtained when the water content is controlled at a suitable ambient temperature during crystallization. acid.
Jinan Sanen Chemical Co., Ltd. was established on March 23, 2001. It sells domestic and imported chemical raw materials hydrochloric acid, sulfuric acid, liquid caustic soda, sodium chlorate, polyaluminum chloride, powdered activated carbon, sodium hypochlorite, potassium permanganate all the year round. Polyacrylamide, and other basic raw materials.
The purity of the reagent sulfuric acid is high, and the impurity content is simply zero. It is designed to be used in chemical tests, chemical analysis.
N-Methyldiethanolamine (MDEA) is commonly used to solve the acid gas containing hydrogen sulfide and CO2 in industrial production. It can absorb hydrogen sulfide and part of CO2.
Acetic acid is used for the synthesis of vinyl acetate, acetate fiber, acetate, metal acetate and halogenated acetic acid, is also an important raw material for pharmaceutical, dye, pesticide and organic synthesis.
Generally speaking, when the human body undergoes aerobic metabolism, glucose will be converted into pyruvate, which enters the tricarboxylic acid cycle to produce energy; at the same time, pyruvate produces lactic acid.
Generally speaking, the human body needs aerobic metabolism. Glucose can be converted into pyruvate, which generates energy through the tricarboxylic acid cycle, and pyruvate generates lactic acid. A small amount of lactic acid is produced during aerobic metabolism.
Acetic acid, commonly known as acetic acid (AcOH) because it is the main component of vinegar, is one of the most important fatty acids. In nature, it occurs in many plants as free or esters. Molecular formula CH3COOH.
Glacial acetic acid is actually anhydrous acetic acid, an organic compound. As an organic acid, acetic acid will condense into ice-like crystals when it is lower than the melting point.
Acetic acid (AcOH) is corrosive and has a stimulating effect on eyes, respiratory tract, esophagus and stomach. It can cause vomiting, diarrhea, paralysis of the circulatory system, and even acidosis, uremia and hematuria, eventually leading to death.
Castor oil is a kind of fatty acid triglyceride, which exists in castor bean seeds, and the content is between 35% and 57.%.
