Description
What is L-glutamic acid?
L-glutamic acid is an optically active form of glutamic acid having L-configuration. It has a role as a nutraceutical, a micronutrient, an Escherichia coli metabolite, a mouse metabolite and a neurotransmitter. It is a glutamine family amino acid, a proteinogenic amino acid, a glutamic acid and a L-alpha-amino acid. It is a conjugate acid of a L-glutamate(1-). It is an enantiomer of a D-glutamic acid.

Usage And Synthesis
Chemical Properties:
L-glutamic acid is a white phosphorus flake crystal. It is odorless with a slightly special sour flavor. L glutamic acid powder is slightly acidic. It is slightly soluble in cold water, easily soluble in water, but almost insoluble in ether, acetone and cold acetic acid and is insoluble in ethanol and methanol.
L-glutamic acid Uses:
1. L glutamic acid powder can be used for the pharmaceutical, food additives, and nutritional supplements.
2. L glutamic acid can be used for biochemical research. In medicine, it can be used for treating hepatic coma, seizures prevention, and reducing ketonuria and ketosis.
3. L glutamic acid powder can be used as salt substitute, nutritional supplements, and flavor enhancer (mainly for meat, poultry, soups and so on). It can also be used as the prevention agent for the production of magnesium ammonium phosphate in shrimp, crabs and other aquatic can with the usage amount of 0.3% to 1.6%. According to the provisions of GB 2760-96, it can be used as a spice.
4. L-glutamate is mainly used for the production of monosodium glutamate, spices, and as a salt substitute, nutritional supplements and biochemical reagents.
