Biochem/physiol Actions

Cystine is the dimeric form of cysteine.[4] 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.[2] L-Cystine is crucial for oxygen production and low density lipoprotein modification by arterial smooth muscle cells.[3] It also has a role in the synthesis of glutathione.[1]
