L-Cysteic acid (Standard)

L-Cysteic acid (Standard) is the analytical standard of L-Cysteic acid. This product is intended for research and analytical applications. L-Cysteic acid is the oxidation product of L-cystine. L-Cysteic acid is a substrate of GADCase/CADCaseII. L-Cysteic acid has high affinity with CADCase I (Km = 0.22 mM) . L-Cysteic acid is taken up by the synaptosome through a high affinity, Na+-dependent transport system[1][2].
