L-cystine, labeled with C-14 on C1, C2, C1', C2'. 14C-L-cystine is commonly used in cystine transport, cystine binding, and pencillin biosynthesis studies.
Cystine is an oxidized dimeric form of the amino acid cysteine. It functions as an antioxidant, aids in protein synthesis and serves as a link allowing proteins to maintain their 3-D structure. Furthermore, cystine is a substrate for the cystine-glutamate transport system.
