General description

Glutamic acid is an amino acid with an acidic side group. It works as a proton donor. Decarboxylation of glutamic acid results in the formation of GABA (γ aminobutyric acid), a potent neurotransmitter. Isotope labeled amino acids are required for the production of isotopically labeled proteins.
