L-Cysteine (hydrochloride)

L-Cysteine hydrochloride is an orally active conditionally essential amino acid, which acts as a precursor for biologically active molecules such as hydrogen sulphide (H2S), glutathione and taurine. L-Cysteine hydrochloride suppresses ghrelin and reduces appetite in rodents. L-Cysteine hydrochloride inhibits Aspergillus flavus growth and AFB synthesis by disrupting cell structure and antioxidant system balance. L-Cysteine hydrochloride enhances relaxant responses of rat aortic rings to NO and reduces responses to endothelium-derived relaxing factor (EDRF)[1][2][3][4].
