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).
