L-homocysteic acid is a homocysteic acid with L-configuration. It has a role as a NMDA receptor agonist. It is an enantiomer of a D-homocysteic acid. L-Homocysteic acid is a sulfur-containing glutamic acid analog and a potent NMDA receptor agonist. It is related to homocysteine, a by-product of methionine metabolism. It belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. Short-term incubation of lymphocytes with homocysteine or its oxidation product homocysteinic acid increased the formation of reactive oxygen species and cell necrosis [HMDB]
