Metabolite Identification

Common Name

Pyro-L-glutaminyl-L-glutamine

Description

Pyro-L-glutaminyl-L-glutamine, also known as 5-oxoprolylglutamine or L-p-glu-L-GLN, belongs to the class of organic compounds known as o-glycosyl compounds. These are glycoside in which a sugar group is bonded through one carbon to another group via a O-glycosidic bond. Pyro-L-glutaminyl-L-glutamine has been detected, but not quantified in, fruits. This could make pyro-L-glutaminyl-L-glutamine a potential biomarker for the consumption of these foods. Pyro-L-glutaminyl-L-glutamine 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 Pyro-L-glutaminyl-L-glutamine.
