Technical Information Amino Acids Glutamic acid

Glutamic acid

Glutamic acid, denoted by the symbol Glu or E (with the ionic form known as glutamate), is an α-amino acid essential for protein biosynthesis in nearly all living organisms. While it is considered a non-essential nutrient for humans, meaning that the body can synthesize sufficient amounts on its own, it holds crucial functions. Glutamic acid is the most abundant excitatory neurotransmitter in the vertebrate nervous system. It serves as a precursor for the synthesis of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter, in GABAergic neurons. Glutamic acid exhibits three optically isomeric forms, with the dextrorotatory l-form typically obtained through hydrolysis of gluten, from waste waters of beet-sugar manufacturing, or through fermentation processes. The glutamate neurotransmitter plays a fundamental role in neural activation. It contributes to the savory umami flavor found in foods and is present in glutamate flavorings like MSG (monosodium glutamate). Glutamic acid is encoded by the codons GAA or GAG.
