Useful:

• Description: Cystinyl-bis-glycine is a dipeptide intermediate in the synthesis of oxidized glutathione that is composed of two cysteinylglycine peptides linked by a disulfide bond. It is formed via nonenzymatic oxidation of cysteinylglycine, a glutathione catabolite produced by γ-glutamyl transpeptidase.
