Metabolite Identification
Common NameAlanylglycine
DescriptionAlanylglycine is a dipeptide composed of alanine and glycine that is found in human urine. It is a breakdown product from endogenous and exogenous proteins. This peptide is generated by dipeptidyl-dipeptidase (or tetrapeptide dipeptidase) which leads to the release of dipeptides from a tetrapeptide (more specifically: Ala-GlyAla-Gly). The enzyme acts more slowly on Ala-AlaAla-Ala and Gly-GlyGly-Gly.
