What is cystine?
Cystine is a naturally occurring amino acid that is formed from the oxidation of two cysteine molecules, which are also amino acids. Cystine is a type of disulfide bond, meaning it is formed when two sulfhydryl (-SH) groups on cysteine molecules are oxidized to form a covalent bond (-S-S-) between the two cysteine molecules.
Cystine is an important structural component of many proteins, especially in structural proteins such as hair, nails, and skin. It is also involved in the formation of connective tissues, enzymes, and hormones.
