Metabolite Identification
Common NameGlutaminylglutamine
DescriptionGlutaminylglutamine, also known as H-L-GLN-L-GLN-OH or QQ, 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. Glutaminylglutamine 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 glutaminylglutamine a potential biomarker for the consumption of these foods. Glutaminylglutamine is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a small amount of articles have been published on Glutaminylglutamine.
