Chemical Information
FooDB NamePhenylalanyltyrosine
DescriptionPhenylalanyltyrosine, also known as F-Y or L-phe-L-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. Phenylalanyltyrosine has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make phenylalanyltyrosine a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Phenylalanyltyrosine.
