Incorporation of Riboflavin into Covalently-bound Flavins in Rat Liver

Abstract

Incorporation of riboflavin into covalently-bound flavins in the liver was investigated using radioactive riboflavin. The incorporation into covalently-bound flavins occurs slowly, while that into noncovalently-bound flavin coenzymes occurs rapidly. The administered riboflavin seemed to be converted first to free coenzyme forms and then to ccvalently-bound flavins.
