Cystine is the dimeric form of cysteine. Cysteine is the source of disulfide linkages in proteins and has a role in sulfur transport. It undergoes rapid oxidation to form cystine at physiological pH. L-Cystine is crucial for oxygen production and low density lipoprotein modification by arterial smooth muscle cells. It also has a role in the synthesis of glutathione.
