| The main physiological function of vitamin B2 is to promote metabolism as a coenzyme. Riboflavin combines with phosphoric acid and a molecular protein to form flavinase. This type of enzyme, also known as dehydrogenase, is important for the metabolism of sugars, lipids, and amino acids, as it mediates the transfer of hydrogen atoms. It is an essential factor for the growth of many animals and microorganisms. |
