The main physiological function of vitamin B2 is to promote metabolism as a coenzyme. Riboflavin binds to phosphoric acid and a molecule of protein to form a flavin enzyme. These enzymes, also known as dehydrogenases, are important in mediating the transfer of hydrogen to the metabolism of sugars, fats, and amino acids. It is essential for the growth of many animals and microorganisms.Vitamin B2 binds to specific proteins to form xanthase. Yellow enzyme plays a role in the transfer of hydrogen in the metabolism of substances and participates in the respiratory process of tissues.
