L-Glutamic Acid (H-Glu-OH, Abbreviated Glu or E) (CAS: 56-86-0) is one of the 20 common α-amino acids constituting the protein. It acts as the precursor of biosynthesis of glutamine, proline and arginine.
Function of Food Grade Additive L-Glutamic Acid
1. Glutamic Acid as an important nutrient for human growth, not only has a special physiological role, but also has a unique feature in the food industry.
2. Glutamic Acid as a flavor enhancer can be used to enhance the flavor of the beverage and food.
3. Glutamic Acid can be used as a nutritional drug. Glutamic acid for hair restorer, can be absorbed by the scalp, prevent hair loss and hair newborn. Glutamic acid to the skin, the treatment of wrinkles is curative.
4. Glutamic Acid can be used in medicine, because glutamic acid is one of the amino acids of protein. Although it is not essential amino acids the human body, it can be used as carbon and nitrogen nutrients involved in the body's metabolism. Glutamic acid has a higher nutritional value.
Application of Food Grade Additive Bulk CAS 56-86-0 99% Purity Amino Acid L-Glutamic Acid Powder
1. L-Glutamic Acid is mainly used in the production of monosodium glutamate, spices, salt and used as a generation agent, nutritional supplement and biochemical reagents, etc.
2. L-Glutamic Acid itself can be used as a drug, to participate in the brain protein and sugar metabolism, promote oxidation process, the goods in the body combined with ammonia into non-toxic l-glutamine, decreased blood ammonia, alleviate the symptoms of hepatic coma. Mainly used in the treatment of hepatic coma and severe liver function not entire, but curative effect is not very satisfied; In combination with antiepileptic drugs to fair treatment by small attacks and psychomotor epilepsy seizures. Racemic drugs used in the production of glutamate, also used as a biochemical reagents, etc.
