  • Name: cystine
  • Description: Cystine is a sulfur-containing amino acid obtained by the oxidation of two cysteine molecules which are then linked via a disulfide bond. It has a role as a human metabolite and a mouse metabolite.... It is an organic disulfide and a cysteine derivative. It is a tautomer of a cystine zwitterion. (CHEBI:17376)
