Riboflavin/ Vitamin B2 Introduction:

Vitamin B2 (chemical formula: C17H20N4O6, formula 376.37), also known as riboflavin, is slightly soluble in water and stable when heated in neutral or acidic solutions. It is the component of the flavonoid auxiliary group in the body (the flavonoid plays the

role of hydrogen transfer in the biological REDOX). When it is lacking, it will affect the biological oxidation of the body and cause metabolic disorders. The lesions are mainly manifested as inflammation of the mouth, eyes and external genitalia, such as

keratitis, labitis, glossitis, eye conjunctivitis and scrotitis, etc., so this product can be used for the prevention and treatment of these diseases. The storage of vitamin B2 in the body is limited, so it should be provided daily by diet. Two properties of vitamin B2 are the main causes of its loss: (1) can be destroyed by light; (2) It can be destroyed by heating in

alkali solution.

Riboflavin/ Vitamin B2 Function:

The main physiological function of vitamin B2 is to promote metabolism as a coenzyme. H&Z® 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.
