L-Cysteine S-sulfate sodium hydrate (Cat No.: I042563) is a modified amino acid derivative where the thiol group of L-cysteine is oxidized to a sulfate, forming a stable sodium salt hydrate. This compound is used in biochemical research to study sulfur metabolism, oxidative stress, and enzyme activity involving sulfur-containing substrates. It may also serve as a precursor or model compound in understanding thiol oxidation and disulfide bond formation. Its water solubility and reactivity make it useful in various in vitro experimental settings.
