cysteine

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.

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, the D-isomer of cysteine, is a powerful inhibitor of E. coli growth and is mediated by D-amino acid oxidase to produce H2S, serving as a neuroprotective agent against cerebellar ataxia. Additionally, D-cysteine can inhibit the growth and cariogenicity of a two-species biofilm formed by Streptococcus mutans and Streptococcus hemoglobin.
