Description

Application

L-Homocysteic acid has been used to study hydrogen peroxide-mediated changes in physiological and pathological conditions in the nervous system.

Biochem/physiol Actions

L-Homocysteic acid (L-HCA) is an endogenous neurotransmitter ligand of NMDA (N-methyl-D-aspartate) receptors. It is an analog of glutamate and competitively suppresses glutamate-cystine (xc^-) antiporter function in neurons, causing decrease in cysteine uptake.
