Photoreactions of Retinol and Derivatives sensitized by Flavins

摘要: CRYSTALLINE riboflavin is present in the eyes of several fishes and mammals (for example, Galago crassicaudatus)1. Its role vision, however, obscure. One possible function may be that a transducer to convert blue light (efficiently absorbed by flavin but not rhodopsin) into energy can utilized rhodopsin producing chemical signal. This conversion achieved trivial process re-emission (the wavelength fluorescence at 530 mµ, which favourable for absorption rhodopsin)2 or direct transfer either singlet–singlet triplet–triplet type.
