Pteridine is a chemical compound composed of fused pyrimidine Pyrimidine is a heterocyclic aromatic organic compound similar to benzene and pyridine, containing two nitrogen atoms at positions 1 and 3 of the six-member ring. It is isomeric with two other forms of diazine and pyrazine Pyrazine is a heterocyclic aromatic organic compound rings. A pteridine is also a group of heterocyclic Heterocyclic compounds are organic compounds containing at least one atom of carbon, and at least one element other than carbon, such as sulfur, oxygen or nitrogen within a ring structure. These structures may comprise either simple aromatic rings or non-aromatic rings. Some examples are pyridine , pyrimidine (C4H4N2) and dioxane (C4H8O2) compounds containing a wide variety of substitutions on this structure. Pterins Pterin is a heterocyclic compound composed of a pyrazine ring and a pyrimidine ring ; the pyrimidine ring has a carbonyl oxygen and an amino group. Several tautomers of pterin exist and are shown below. As a group, pterins are compounds that are derivatives of 2-amino-4-oxopteridine, with additional functional groups attached to the pyrazine ring and flavins are classes of substituted pteridines that have important biological activity.
