cysteine hydrazide

Cysteine hydrazide is an enrichment tool for the mass spectrometric characterization of bacterial-free oligosaccharides.

L-Cysteine hydrochloride hydrate (L-Cysteine hydrochloride monohydrate) is a conditionally essential amino acid, which acts as a precursor for biologically active molecules such as hydrogen sulphide (H2S), taurine and glutathione. L-Cysteine hydrochloride hydrate suppresses ghrelin and reduces appetite in rodents and humans.

D-Cysteine is the D-isomer of cysteine and a powerful inhibitor of the growth of E. coli. D-cysteine is mediated by D-amino acid oxidase to produce H2S, and is a neuroprotective agent against cerebellar ataxia. D-cysteine can inhibit the growth and cariog

L-Cysteine (L-(+)-Cysteine) is a non-essential sulfur-containing amino acid in humans. L-Cysteine is important for protein synthesis, detoxification, and diverse metabolic functions. Found in beta-keratin, the main protein in nails, skin, and hair, L-Cysteine is important in collagen production, as well as skin elasticity and texture. Also required in the manufacture of amino acid taurine, L-Cysteine is a component of the antioxidant glutathione, and plays a role in the metabolism of essential biochemicals such as coenzyme A, heparin, and biotin.

Cysteine monohydrate is a semi-essential proteinogenic amino acid.
