Biochem./physiol. Wirkung

Pterine consists of pyrazine and pyrimidine with substitutions in keto and amino group. Pterine is present in all organisms including cyanobacteria. It acts as a cofactor for redox enzymes and serves as a precursor for folic acid synthesis. Pterine from the butterfly wings absorb light and elicit incoherent scattering. Pterine induces alterations in DNA by hydroxylation of deoxyguanosine.
