History of glutamic acid use:
Glutamate gets its name because it was originally made from grains. It is widely distributed and is found in almost all protein components. Protein hydrolysis yields glutamic acid. Colorless plate crystal, isoelectric point 3.3, soluble in water, insoluble in benzene, ether and other organic solvents, aqueous solution is acidic, acidic amino acids. In physiology, glutamic acid can combine with glycine and cysteine to form glutathione which has important physiological functions. Glutamic acid has umami flavor, its sodium salt is MSG. MSG in high heat will decompose, not strong heat. Monosodium glutamate was first discovered by Ikeda, a Japanese chemist. A chance, he drank kelp soup taste of umami, after research, with 100 kilograms of kelp extract to get 2 grams of sodium glutamate. It was later mass-produced in Japan and called Ajinomoto. China in the 1930s by Shanghai Tianchu monosodium glutamate Factory was the first to produce MSG, exported to countries to win a reputation. After hydrolyzing gliadin or casein, the pH value of the solution is adjusted to 3.3 to obtain glutamic acid precipitation. After separation, sodium hydroxide is added to form monosodium glutamate. MSG can also be synthesized artificially, but the cost is expensive, and is usually still obtained by the protein hydrolysis method described above. After the 1960s, Japan used microbial fermentation to produce glutamic acid. They put bacteria of Bacillus micrococcus, Bacillus and Bacillus into carbohydrate compounds (mainly starch and glucose), and then add urea, ammonium sulfate, ammonium chloride and biotin and other nutrients. The bacteria secreted a large amount of glutamate to produce monosodium glutamate. At present, China has also adopted the fermentation method to produce MSG. Glutamate also binds to ammonia in the blood to make it non-toxic. It is also used to treat liver coma and convalescent liver insufficiency. 

Use:
L-glutamic acid is mainly used in the production of monosodium glutamate, flavoring, and used as a substitute for salt, nutritional supplements and biochemical reagents. L-glutamic acid itself can be used as a drug to participate in the metabolism of protein and sugar in the brain and promote the oxidation process. The product combines with ammonia in the body to form non-toxic glutamide, which makes Chemicalbook blood ammonia decrease and reduces the symptoms of liver coma. It is mainly used to treat hepatic coma and severe hepatic insufficiency, but the effect is not very satisfactory. Combined with antiepileptic drugs, it can treat minor seizures and psychomotor seizures. Racemic glutamate is used in the production of drugs, but also used as a biochemical reagent, etc.
