Riboflavin, also kent as vitamin B2 is an easily absorbed coloured micronutrient wi a key role in maintainin health in humans an ainimals. It is the central component o the cofactors FAD an FMN, an is therefore required bi aw flavoproteins. As such, vitamin B2 is required for a wide variety o cellular processes. It plays a key role in energy metabolism, an for the metabolism o fats, ketone bodies, carbohydrates, an proteins.
The name "riboflavin" comes frae "ribose" (the succar whose reduced fairm, ribitol, fairms pairt o its structur) an "flavin", the ring-moiety which imparts the yellae colour tae the oxidized molecule (frae Latin flavus, "yellae"). The reduced fairm, which occurs in metabolism alang wi the oxidized fairm, is colourless.
Riboflavin is baist kent visually as the vitamin which imparts the orange colour tae solid B-vitamin preparations, the yellae colour tae vitamin supplement solutions, an the unusual fluorescent-yellae colour tae the urine o persons who supplement wi heich-dose B-complex preparations (no ither vitamin imparts ony colour tae urine).
