Metabolite Identification
Common NameTyrosyl-Leucine
DescriptionTyrosyl-leucine, also known as y-L dipeptide or tyr-leu, 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. Tyrosyl-leucine is possibly soluble (in water) and a very strong basic compound (based on its pKa).
