Biological Activity: L-Cysteine (Cysteine) is an orally active conditionally essential amino acid with hypoglycemic effects, which acts as a precursor for biologically active molecules such as hydrogen sulphide (H2S), glutathione and taurine. L-Cysteine promotes the proliferation and differentiation of neural stem cells via the CBS/H2S pathway. L-Cysteine suppresses ghrelin and reduces appetite in rodents and humans. L-Cysteine can be used as an anorectic agent[1][2][3][4].
