Description

White solid

Glutamic acid is an alpha-amino acid that is glutaric acid bearing a single amino substituent at position 2. It has a role as a fundamental metabolite. It is an alpha-amino acid and a polar amino acid. It contains a 2-carboxyethyl group. It is a conjugate acid of a glutamate(1-).|A non-essential amino acid naturally occurring in the L-form. Glutamic acid is the most common excitatory neurotransmitter in the CENTRAL NERVOUS SYSTEM.

ChEBI: An alpha-amino acid that is glutaric acid bearing a single amino substituent at position 2.
