Metabolite Identification
Common NameGlycyl-glycine
DescriptionGlycyl-glycine, also known as gly-gly or GLY2, 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. Glycyl-glycine exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule.
