Cystine

Cystine is an amino acid found in both plants and animals.

Cystine is formed by the oxidization of two monomers of Cysteine, forming the dimer amino acid. Cystine's most common function is in protein formation. Thiols engineered to reduce disulfide bonds (such as 2-Mercaptoethanol or

DL-Dithiothreitol) can revert Cystine back into Cysteine.
