Explain Some Functions of Riboflavin?

Protective role: Riboflavin protects the octodermal tissues and prevents lesions  of the skin, eye and nervous system. Riboflavin ameliorates cardiac damage and also has antimalarial effects.

Regulatory functions: Riboflavin is concerned with the regulatory functions of  some hormones involved in carbohydrate metabolism.

Other function: Riboflavin interrelates with other B vitamins, notably niacin, which requires FAD for its formation from tryptophan, and vitamin B6 which requires FMN for conversion of the phosphates of pyridoxine and pyridoxamine to the coenzyme pyridoxal 5'-phosphate (PLP). Riboflavin deficiency slows down the uptake of pyridoxine and decreases the conversion of pyridoxine to its metabolites.
