生物活性

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].

Animal Model: Male Wistar rats following an overnight 16-h fast[1]
Dosage: 1-4 mmol/kg
Administration: p.o. or i.p., a single dose for 1 h

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
