Biochem/physiol Actions

Riboflavin is a key component of the redox cofactors flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN) that are used by a wide variety of flavoprotein oxidoreductases, dehydrogenase(s), decarboxylase(s) and electron transporters. Riboflavin is involved in various cellular processes, including β oxidation in lipid metabolism, glucose metabolism, protection from cellular oxidative injury, DNA and RNA metabolism, gluconeogenesis, erythropoiesis and generation of corticosteroids. Riboflavin deficiency causes ariboflavinosis with symptoms such as sore throat, hyperemia, edema of oral and mucous membranes, cheilosis and glossitis.
