Chemical compound
Pteridine is an aromatic organic compound composed of fused pyrimidine and pyrazine rings. Pteridines also constitute a group of heterocyclic compounds containing a wide variety of substituents on this parent structure. Pterins and flavins are classes of substituted pteridines that have diverse biological roles.[2]
