Metabolite Identification
Common NameArginyl-Cysteine
DescriptionArginyl-cysteine, also known as R-c dipeptide or arg-cys, belongs to the class of organic compounds known as dipeptides. These are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Arginyl-cysteine is possibly soluble (in water) and a very strong basic compound (based on its pKa).
