Description

Product Detail

Basic Information
- Definition and Structure：L - Glutamic acid is an α - amino acid with the chemical formula C₅H₉NO₄ and a molecular weight of 147.13. It contains an amino group (-NH₂) and two carboxyl groups (-COOH) in its structure, and its chemical name is (S)-2 - aminopentanedioic acid.
- CAS Number：56 - 86 - 0.
Physicochemical Properties
- Appearance：Usually white crystalline powder.
- Melting Point：205℃ (decomposition).
- Solubility：Slightly soluble in cold water and easily soluble in hot water.
- Acidity and Alkalinity：It has acidity. The two carboxyl groups in the molecule can dissociate hydrogen ions in aqueous solution, and its isoelectric point is 3.22.
Physiological Functions
- Involved in Protein Synthesis：It is one of the basic units that make up proteins. During the process of protein biosynthesis, it is connected to other amino acids through peptide bonds to form protein molecules with specific functions. The content and arrangement order of L - glutamic acid in different proteins are different, which determines the diversity of protein structures and functions.
- Neurotransmitter Function：In the nervous system, L - glutamic acid is an important excitatory neurotransmitter that transmits signals between neurons and plays a key role in the cognitive, learning, and memory functions of the brain. It is involved in regulating synaptic plasticity and neuronal excitability and is closely related to the normal physiological functions of the brain.
Sources
- Food Sources：There are many foods rich in L - glutamic acid, such as meat, fish, dairy products, beans, nuts, and some vegetables and fruits. For example, kelp, mushrooms, soybeans, and milk are all good sources of glutamic acid. In addition, in some fermented foods such as soy sauce and miso, there is also a high content of glutamic acid, which is produced by the decomposition of proteins by microorganisms during the fermentation process.
- Synthesis in the Body：The human body can synthesize L - glutamic acid from other substances, and it belongs to non - essential amino acids. In cells, it can be produced by the transamination of α - ketoglutaric acid.
Application Fields
- Food Industry：As a food additive, L - glutamic acid and its sodium salt (such as monosodium glutamate, i.e., sodium glutamate) are widely used to enhance the umami taste of food. It can significantly improve the flavor of food and make the food more delicious, so it has a wide range of applications in cooking and food processing. In addition, L - glutamic acid can also be used as a nutritional fortifier to increase the nutritional value of food.
- Feed Industry：It is an important additive in animal feed. It can improve the growth performance and feed utilization rate of animals and promote the growth and development of animals. In aquaculture, it also has a positive effect on the growth and immunity of aquatic animals such as fish and shrimp.
- Pharmaceutical Field：It is often used as an intermediate in drug synthesis for the preparation of some drugs for the treatment of liver diseases, neurological diseases, etc. For example, L - glutamic acid can be used to treat hepatic encephalopathy and improve liver function by promoting the metabolism of ammonia. In addition, it is also used in health products and has the effects of improving memory and anti - fatigue.

- CAS Number：56 - 86 - 0.
Physicochemical Properties
- Appearance：Usually white crystalline powder.
- Melting Point：205℃ (decomposition).
- Solubility：Slightly soluble in cold water and easily soluble in hot water. It is insoluble in organic solvents such as ethanol, ether, and acetone.

It is involved in regulating synaptic plasticity and neuronal excitability and is closely related to the normal physiological functions of the brain.
- Metabolic Regulation：L - glutamic acid plays an important role in the body's metabolic process. It can participate in the urea cycle, help the body excrete ammonia, and maintain the body's nitrogen balance. At the same time, it is also an important precursor for the synthesis of other amino acids such as glutamine and proline, and has an important position in amino acid metabolism and biosynthesis.
