L-glutamic acid
Product introduction:
Medically, glutamate is mainly used to treat hepatic coma and improve children's intellectual development. In the food industry, monosodium glutamate is a commonly used food freshener, and its main component is sodium glutamate. In the past, wheat gluten was mainly used in the production of monosodium glutamate (glutamic acid) hydrolysis method is used for large-scale production. Now, microbial fermentation method is used for large-scale production. L-glutamic acid is mainly used for the production of monosodium glutamate and spices, as well as salt substitutes, nutritional supplements and biochemical reagents. L-glutamic acid itself can be used as drugs to participate in the metabolism of protein and sugar in the brain and promote the oxidation process. This product combines with ammonia to synthesize non-toxic glutamine in the body, so as to reduce blood ammonia and reduce blood ammonia Mild liver coma. L-glutamic acid is widely used. As a drug, it can treat liver coma. It can also be used to produce monosodium glutamate, food additives, spices and biochemical research. Glutamate is one of the basic amino acids of nitrogen metabolism in biological body, which is of great significance in metabolism. L-glutamate is the main component of protein, and glutamate is common in nature. Glutamate is one of the structural amino acids of protein or peptide and free amino acid. L-type amino acid is delicious. L-glutamic acid, also known as "glutamic acid" or "fulvic acid", is produced by fermentation with sugar as raw material, microbial fermentation, and separation by "isoelectric point extraction" and "ion exchange resin".
