    Excited flavin and pterin coenzyme molecules in evolution

    Excited flavin and pterin molecules are active in intermolecular energy transfer and in photocatalysis of redox reactions resulting in conservation of free energy. Flavin-containing pigments produced in models...

    Investigation of the photochemical properties of biopterin and its reduced forms

    UV irradiation (270–390 nm, 20 min, I = 3.2 W m−2) of deaerated biopterin solution containing electron donor (Na2-EDTA) led to the formation of 7,8-dihydrobiopterin (H 2
