Not considered one of the 20 amino acids, cystine (also known as L-cystine) is a sulfurcontaining derivative obtained from oxidation of cysteine amino acid thiol side chains. It functions as an antioxidant and protects tissues against radiation and pollution, slowing the aging process. It also aids protein synthesis. Cystine is abundant in many proteins of skeletal tissues and skin and is found in insulin and digestive enzymes chromotrypsinogen A, papain, and trypsinogen. It has been claimed that L-cysteine has anti-inflammatory properties, that it can protect against various toxins, and that it might be helpful in osteoarthritis and rheumatoid arthritis (RA). More research will have to be done before L-cysteine can be indicated for any of these conditions. Research to date has mostly been in animal models.
