Glutamic acid (abbreviated as Glu or E) is one of the 20-22 proteinogenic amino acids, and its codons are GAA and GAG. It is a non-essential amino acid. The carboxylate anions and salts of glutamic acid are known as glutamates. In neuroscience, glutamate is an important neurotransmitter that plays the principal role in neural activation. == Chemis...

Glutamic acid: An amino acid, one of the 20 building blocks of protein. A nonessential amino acid, glutamic acid is present in many animal and plant proteins. It is involved in ammonia metabolism and serves as a neurotransmitter. Glutamic acid was isolated from wheat gluten in 1866 and first synthesized in 1890. Symbol: Glu.
