Chemical Information
FooDB NameRiboflavine
DescriptionRiboflavin, also known as lactoflavin or vitamin B2, belongs to the class of organic compounds known as flavins. Flavins are compounds containing a flavin (7,8-dimethyl-benzo[g]pteridine-2,4-dione) moiety, with a structure characterized by an isoalloaxzine tricyclic ring. It occurs in the free form only in the retina of the eye, in whey, and in urine; its principal forms in tissues and cells are as flavin mononucleotide and flavin-adenine dinucleotide. Riboflavin is a drug which is used for the treatment of ariboflavinosis (vitamin b2 deficiency). The antioxidant activity of riboflavin is principally derived from its role as a precursor of FAD and the role of this cofactor in the production of the antioxidant reduced glutathione. Riboflavin is an extremely weak basic (essentially neutral) compound (based on its pKa). Riboflavin exists in all living species, ranging from bacteria to humans. Binds to riboflavin hydrogenase, riboflavin kinase, and riboflavin synthase. In humans, riboflavin is involved in the metabolic disorder called the medium chain acyl-coa dehydrogenase deficiency (mcad) pathway. Outside of the human body, Riboflavin is found, on average, in the highest concentration within a few different foods, such as saffrons, saskatoon berries, and leavening agents and in a lower concentration in grape wines, hippoglossus (common halibut), and spiny lobsters. Riboflavin has also been detected, but not quantified in, several different foods, such as bog bilberries, lowbush blueberries, greenthread tea, nanking cherries, and black radish. This could make riboflavin a potential biomarker for the consumption of these foods. Riboflavin is a potentially toxic compound. Nutritional factor found in milk, eggs, malted barley, liver, kidney, heart, and leafy vegetables. The richest natural source is yeast.
