L-Glutamic acid (Glu/E), scientific name α - aminoglutarate, is one of the 20 natural amino acids synthesized in proteins, with the molecular formula C ₅ H ₉ NO ₄, CAS 56-86-0。
1、 Attributes
• Physical properties: White crystalline powder, slightly soluble in water, with a special umami taste, odorless, L-type is a natural active configuration.
• Physiological role: The mammalian central nervous system is the main excitatory neurotransmitter and a precursor to the synthesis of the inhibitory neurotransmitter GABA; Participate in nitrogen metabolism, combine with ammonia to produce glutamine, and reduce blood ammonia.
2、 Purpose:
1. Food industry: the core raw material for producing monosodium glutamate (MSG); Used as a nutritional supplement, salt substitute, and anti crystallization agent for canned seafood (0.3% -1.6%), in compliance with GB2760 standard.
2. Medical field: Assisted treatment for hepatic coma, reducing blood ammonia levels; Improve children's intellectual development; Combined use with antiepileptic drugs for adjuvant treatment of epileptic seizures.
3. Biochemistry and scientific research: amino acid nutrition sources for cell culture media; Commonly used reagents in neuroscience and metabolic research.
3、 Production process
The mainstream method is microbial fermentation (using sugar as raw material, such as corn starch), which involves isoelectric point extraction and ion exchange separation, with large scale and low cost.
Traditional methods include protein hydrolysis (such as wheat gluten), which is now less commonly used.
