Vitamin B2 ( riboflavin )
Riboflavin or vitamin B2 is an essential nutrient in human nutrition and plays a key role in the production of energy. Vitamin B2 is needed to process amino acids and fats, activate vitamin B6 and folic acid, and help convert carbohydrates into the fuel the body runs on. Under some conditions, vitamin B2 can act as an antioxidant. Vitamin B2 is an intermediary the transfer of electrons in the cellular oxidation-reduction reactions which generate energy from protein, carbohydrate and fat. The riboflavin coenzymes are also important for the transformation of vitamin B6 and folic acid into their respective active forms, and for the conversion of tryptophan into niacin. Riboflavin is involved in energy production as part of the electron transport chain that produces cellular energy.
