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.

Seventy-six compounds of biological interest for the diagnosis of inherited disorders of amino acids (AA) metabolism have previously been demonstrated to be detectable in positive mode electrospray ionisation tandem mass spectrometry (ESI-MS/MS), after separation by ion-pairing reversed-phase liquid chromatography (RPLC).

Fast photochemical oxidation of proteins (FPOP) is a MS-based method that has proved useful in studies of protein structures, interactions, conformations, and protein folding. The success of this method relies on the irreversible labeling of solvent-exposed amino acid side chains

L-Homocysteic acid (L-HCA) has been proposed as a natural transmitter at the N-methyl-D-aspartate (NMDA) subtype of excitatory amino acid receptor based on recent evidence that L-HCA occurs L-HCA occurs naturally in the mammalian CNS, is released from K+ stimulated brain

The effects of ionophoretically applied L-homocysteate (L-HCA), L-glutamate (L-Glu) and N-methyl-D-aspartate (NMDA) were compared in rat neocortical neurons recorded intracellularly in vitro. The firing pattern and the time course of membrane depolarization induced by L-HCA resembled those of NMDA responses.
