L-Glutamic acid Usage And Synthesis

One of the 20 kinds of common amino acid Glutamate is one of the 20 common α-amino acids constituting the protein. It acts as the precursor of biosynthesis of glutamine, proline and arginine. It is divided into three forms including L-handed, right-handed and racemic body. The left handed is L-glutamate which is the coding amino acid participating in protein synthesis and is a kind of non-essential mammalian amino acids, and can be converted from glucose inside the body. At room temperature, it is a white or colorless flaky crystal, slightly acidic, and is non-toxic. It is slightly soluble in cold water but easily soluble in hot water and almost insoluble in ether, acetone and acetic acid as well as in ethanol and methanol. It undergoes sublimation at 200 ℃ and decomposed at 247 ℃-249 ℃ with a density of 1.538g/cm3 and optical rotation being + 37-+ 38.9 (25 ℃). L-glutamate has wide applications. It is a kind of drug can be used for treating hepatic coma. It can also be used to produce MSG (monosodium glutamate), research food additives, spices and also used for biochemistry studies. The production of glutamate is based on the microbial fermentation using carbohydrate as the raw material and applying "Isoelectric point extraction" plus "ion exchange resin" for separate it. 

Glutamate is ubiquitous in nature. Glutamate salt is distributed in a variety of food as well as in human body. It is both a kind of amino acid constituting protein or peptide and free amino acids. Its L-amino acids form has delicious taste. 

Glutamate was first discovered by Rizzo Johnson in 1856. It is a colorless crystal with good flavor and is slightly soluble in water and soluble in hydrochloric acid solution. It has an isoelectric point of 3.22. It is presented a large number of proteins in the grain. Its content in animal brain is also high. Glutamate plays an important role in the protein metabolism in vivo and participates in many important biochemical reactions of animals, plants as well as microorganisms.
