Metabolite Identification
Common NameAlanyl-Tyrosine
DescriptionAlanyl-tyrosine, also known as a-y dipeptide or ala-tyr, 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. Alanyl-tyrosine is possibly soluble (in water) and a very strong basic compound (based on its pKa).
