Molecular Weight: 147.13 

EINECS Number: 200-293-7

Glutamate is one of the 20 common alpha amino acids that make up proteins. As a precursor of glutamine, proline and arginine. It is divided into three forms: L-body, D-body and racemate. L-body is L-glutamic acid. L-glutamic acid is a coded amino acid in protein synthesis. It is a non-essential amino acid in mammals and can be derived from glucose in the body. Transformed. It is a white or colorless scaly crystal at room temperature, slightly acidic and non-toxic. Slightly soluble in cold water, soluble in hot water, almost insoluble in ether, acetone and cold acetic acid, and insoluble in ethanol and methanol. Sublimation at 200℃, decomposition at 247℃-249℃, density 1.538g/cm3, optical rotation +37－+38.9(25℃). L-glutamic acid has a wide range of uses. As a medicine, it can treat hepatic coma. It can also be used to produce monosodium glutamate (sodium glutamate), food additives, spices, and for biochemical research. L-glutamic acid is prepared by using carbohydrates as raw materials through microbial fermentation, using "isoelectric point extraction" and "ion exchange resin" separation method.
