Metabolite Identification
Common NamePhenylalanylisoleucine
DescriptionPhenylalanylisoleucine is a dipeptide composed of phenylalanine and isoleucine. It is an incomplete breakdown product of protein digestion or protein catabolism. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Some dipeptides are known to have physiological or cell-signalling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis.
