Biochem/physiol Actions

L-Cysteic acid is a sulfur containing aspartate analogue that may be used as a competitive inhibitor of the bacterial aspartate:alanine antiporter (AspT) exchange of aspartate and in other aspartate biological systems. L-Cysteic acid is used in monomeric surfactant development.
L-cysteic acid is an oxidation product of L-cysteine. L-Cysteic acid, an analogue of cysteine sulfinic acid, may be used in studies of excitatory amino acids in the brain, such as those that bind to cysteine sulfinic acid receptors. L-Cysteic acid is a useful agonist at several rat metabotropic glutamate receptors (mGluRs).

Amino acids provide the most universal and important inhibitory (gamma-aminobutyric acid (GABA), glycine) and excitatory (glutamate, aspartate, cysteic acid, cysteine sulphinic acid) neurotransmitters in the brain. An anticonvulsant action may be produced (1) by enhancing inhibitory (GABAergic) processes, and (2)

Moderate hyperhomocysteinemia is associated with several diseases, including coronary artery disease, stroke, Alzheimer's disease, schizophrenia, and spina bifida. However, the mechanisms for their pathogenesis are unknown but could involve the interaction of homocysteine or its metabolites with molecular targets such
