Metabolite Identification
Common Name7-Hydroxy-6-methyl-8-ribityl lumazine
Description7-Hydroxy-6-methyl-8-ribityl lumazine, also known as masuda's compound V or RL-6-me-7-OH, 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. 7-Hydroxy-6-methyl-8-ribityl lumazine is an extremely weak basic (essentially neutral) compound (based on its pKa). In humans, 7-hydroxy-6-methyl-8-ribityl lumazine is involved in riboflavin metabolism.
