Glutamic acid (abbreviated as Glu or E) is one of the 20-22 proteinogenic amino acids, and its codons are GAA and GAG. Non-essential amino acid for human development; referred to as an excitatory amino acid (EAA) due to its role in neurotransmission. It is an excitatory amino acid which acts as a neurotransmitter at fast synapses; agonist at kainate, NMDA and quisqualate receptors. The carboxylate anions and salts of glutamic acid are known as glutamates.
