Metabolite Identification
Common NameAlanyl-Histidine
DescriptionAlanyl-histidine, also known as a-H dipeptide or ala-his, 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-histidine is possibly soluble (in water) and a very strong basic compound (based on its pKa).
