Product Description

Wholesale factory supplies CAS 83-88-5 vitamin B2 riboflavin 

Product Description

The main physiological function of vitamin B2 is to act as a coenzyme to promote metabolism. Riboflavin combines with phosphoric acid and protein molecules to form flavozyme. These enzymes, also known as dehydrogenases, play an important role in mediating the metabolism of hydrogen to sugars, fats, and amino acids. It is essential for the growth of many animals and microorganisms. Vitamin B2 combines with specific proteins to form xanthogenase. Yellow enzymes play a role in the transfer of hydrogen in material metabolism and participate in the respiration process of tissues.
