Metabolite Identification
Common NameValyl-Arginine
DescriptionValyl-arginine, also known as V-R dipeptide or val-arg, 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. Valyl-arginine is possibly soluble (in water) and a very strong basic compound (based on its pKa).
