Metabolite Identification
Common NameGlutaminyllysine
DescriptionGlutaminyllysine, also known as Q-K dipeptide or GLN-lys, 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. Glutaminyllysine has been detected, but not quantified in, several different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), domestic pigs (Sus scrofa domestica), and milk (cow). This could make glutaminyllysine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Glutaminyllysine.
