Metabolite Identification
Common NameGlutaminylisoleucine
DescriptionGlutaminylisoleucine, also known as Q-i dipeptide or GLN-ile, 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. Glutaminylisoleucine 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 glutaminylisoleucine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Glutaminylisoleucine.
