ABOUT L-GLUTAMIC ACID
VIADD CHEMICAL company is one professional L-GLUTAMIC ACID supplier, distibutor and exporter from China, welcome get L-GLUTAMIC ACID price by email: sales@viaddchem.com
L-Glutamic Acid, CAS# 56-86-0, is one of many non-essential amino acids that are produced in the body. Downstream derivatives of L-glutamic acid include salts and carboxylate anions, also known as glutamates. Glutamates and other L-glutamic acid derivatives are used in foods, flavorings, nutritional supplements and pharmaceutical products.
L-Glutamic acid occurs naturally in many protein-rich foods and is typically used as a flavoring agent when added to food products in its crystalline salt state, Monosodium Glutamate-MSG. Although L-glutamic acid is naturally present in numerous foods that contain protein, it cannot be tasted in these foods unless it is unbound (i.e. not part of a long protein chain). In its unbound form, L-glutamic acid is gives off the taste known as umami, which is a rich and savory flavor tasted at the back of the tongue.
L-Glutamic acid is a member of the amino acids chemical family, and amino acids are the building blocks of proteins. Long protein chains typically comprise several different amino acids, and each type of amino acid has different properties and effects. Many amino acids are essential amino acids, meaning that they are not produced in the body and must be obtained from other sources (protein-rich foods are sources of essential amino acids). L-glutamic acid is a non-essential amino acid because it is produced naturally in the body. A non-essential amino acid. Its salt form (glutamate) is an important neurotransmitter that plays a key role in long-term potentiation and is important for learning and memory. It is also a key molecu le in cellular metabolism.

【Uses of L-Glutamic Acid】
1. It can be used for the pharmaceutical, food additives, and nutritional supplements.
2. It can be used for biochemical research. In medicine, it can be used for treating hepatic coma, seizures prevention, and reducing ketonuria and ketosis.
3. It 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. L-glutamate itself can be used as drugs and is involved in protein and carbohydrate metabolism in the brain, promoting the oxidation process. This product can combine with ammonia in the body into non-toxic glutamine, causing decreasing ammonia and reducing the symptoms of hepatic coma. It is mainly used for the treatment of hepatic coma and severe hepatic dysfunction. However, the efficacy is not satisfied; Combination with antiepileptic drugs can treat seizures and psychomotor seizures. Racemic glutamate can be used in the production of drugs as well as being used as biochemical reagents.
5. One of its sodium salts: sodium glutamate is used as seasoning. Commodities include monosodium glutamate and gourmet powder.
【Application of L-Glutamic Acid】
L-glutamic acid is mainly used to treat hepatic coma in medicine and is also used to improve children's mental development. In the food industry, MSG is commonly used as a fresh-keeping agent for instruments, and its main component is L-glutamic acid sodium salt. The past, the production of MSG mainly wheat gluten (gluten) hydrolysis method, is now using microbial fermentation for large-scale production.
