Open Data Verified Data
- This product is white crystal or crystalline powder; Taste slightly acid. Density 1. 538g/cm3. Sublimation at 200 C, 247~249 C decomposition. Soluble in hot water, slightly soluble in water at room temperature (0.84%,25 ° C), insoluble in ethanol, acetone, ether.
- glutamic acid is a non-essential amino acid that is produced in humans from a-ketoglutarate. It is one of the essential amino acids for metabolism in the body. Under the catalysis of glutamine synthetase, it can react with ammonia to generate glutamine, which is excreted by urine to relieve ammonia toxicity. It also participates in brain protein and sugar metabolism, and promotes oxidation process, improves the function of the central nervous system; In the body it can be converted into acetone or glucose, thereby increasing blood sugar, reducing gluconeogenesis, thereby reducing lipolysis and reducing ketone bodies.
