Metabolite Identification
Common Name6,7-Dimethyl-8-(1-D-ribityl)lumazine
Description6,7-Dimethyl-8-(1-D-ribityl)lumazine 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. 6,7-Dimethyl-8-(1-D-ribityl)lumazine is an extremely weak basic (essentially neutral) compound (based on its pKa). 6,7-Dimethyl-8-(1-D-ribityl)lumazine exists in all living organisms, ranging from bacteria to humans. In humans, 6,7-dimethyl-8-(1-D-ribityl)lumazine is involved in riboflavin metabolism. Outside of the human body, 6,7-dimethyl-8-(1-D-ribityl)lumazine has been detected, but not quantified in, several different foods, such as quinoa, arrowhead, conchs, watermelons, and Elliott's blueberries. This could make 6,7-dimethyl-8-(1-D-ribityl)lumazine a potential biomarker for the consumption of these foods. 6,7-Dimethyl-8-(1-D-ribityl)lumazine is an intermediate in riboflavin metabolism. 6,7-Dimethyl-8-(1-D-ribityl)lumazine is the second to last step in the synthesis of ribitol and is converted from 4-(1-D-ribitylamino)-5-amino-2,6-dihydroxypyrimidine via the enzyme riboflavin synthase beta chain. It is then converted into riboflavin via the enzyme riboflavin synthase alpha chain (EC 2.5.1.9).
