Cysteine, another non-essential amino acid, is one of the few amino acids that contains sulfur. The functions of cysteine and NAC include being a component of the important antioxidant glutathione and helping to produce the amino acid taurine. In addition, cysteine strengthens the protective lining of the stomach and intestines and has a role in the proper function of the immune system. R group is a generic label for a side chain which can be anything; however, it is typically stable and covalently linked to the adjoining atom in cysteline it is disulfide.
The systemic name for Cystaine is (2R)-2-amino-3-sulfanyl-propanoic acid
