Metabolite Identification

Common Name

Dihydropteridine

Description

Dihydropteridine belongs to the class of organic compounds known as pteridines and derivatives. These are polycyclic aromatic compounds containing a pteridine moiety, which consists of a pyrimidine fused to a pyrazine ring to form pyrimido(4,5-b)pyrazine. Dihydropteridine exists in all living organisms, ranging from bacteria to humans. In humans, dihydropteridine is involved in the pterine biosynthesis pathway. Dihydropteridine 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 dihydropteridine a potential biomarker for the consumption of these foods. Dihydropteridine is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on Dihydropteridine.
