Riboflavin, forby kent as vitamin B2 is an easy absorbit 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 syne required bi aw flavoproteins. In that wey, 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 whase reduced fairm, ribitol, fairms pairt o its structur) an "flavin", the ring-moiety whilk imparts the yellae colour tae the oxidized molecule (frae Latin flavus, "yellae"). The reduced fairm, whilk occurs in metabolism alang wi the oxidised fairm, is colourless.
Riboflavin is baist kent visually as the vitamin whilk imparts the orange colour tae solit B-vitamin preparations, the yellae colour tae vitamin supplement solutions, an the orra fluorescent-yellae colour tae the urine o persons wha supplement wi heich-dose B-complex preparations (nae ither vitamin imparts ony colour tae urine).
