Metabolite Identification
Common NameLysyl-Glycine
DescriptionLysyl-glycine, also known as K-g dipeptide or lys-gly, 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. Lysyl-glycine is possibly soluble (in water) and a very strong basic compound (based on its pKa).
