Description:
The conflicting results were eventually found to be due,in part, to deficiencies in study animals not just of vitamin B2,but also vitamin B3 (niacin), the cause of human forms of pellagra,and/or vitamin B6 (pyridoxine), another cause of dermatitis. Likewise, treatments with vitamin B2 were inconsistent because the early sources of this vitamin contained otherB vitamins. Vitamin B2 was eventually isolated from eggwhites in 1933 and produced synthetically in 1935. Thename riboflavine was officially accepted in 1960; althoughthe term was in common use before then. In 1966, IUPAC changed it to riboflavin, which is in common use today.Riboflavin is synthesized by all green plants and by mostbacteria and fungi. Therefore, riboflavin is found, at least insmall amounts, in most foods. Foods that are naturally highin riboflavin include milk and other dairy products, meat,eggs, fatty fish, and dark green vegetables.
Chemically, riboflavin is an N-glycoside of flavin, alsoknown as lumichrome, and the sugar, ribitol .Flavin is derived from the Latin word flavus for "yellow"because of the yellow color of its crystals and yellow fluorescenceunder UV light. Riboflavin is heat stable but easilydegraded by light. Its systematic names are 7,8-dimethyl-10-ribitylisoalloxazine and 7,8-dimethyl-10-(D-ribo-2,3,4,5-tetrahydroxypentyl)isoalloxazine.
Usage:
Vitamin B2 (riboflavin) is produced by yeast from glucose, urea, and mineral salts in an aerobic fermentation.
