6.Introduction:
Vitamin B2, also called riboflavin, is slightly soluble in water and stable when heated in neutral or acidic solutions. It is a component of the prosthetic group of yellow enzymes in the body (yellow enzymes play a role of hydrogen transfer in biological redox). When lacking, it will affect the body's biological oxidation and cause metabolic disorders. The lesions are mostly inflammation of the mouth, eyes and external genitals, such as angular cheilitis, cheilitis, glossitis, conjunctivitis and scrotum, so this product can be used for the prevention and treatment of the above diseases. The storage of vitamin B2 in the body is very limited, so it must be provided by the diet every day.
1. The main physiological function of vitamin B2 is to promote metabolism as a coenzyme. Riboflavin is combined with and a molecule of protein to form a yellow enzyme. This type of enzyme is also called dehydrogenase. The important thing is that very mediated hydrogen atom transfer is important for the metabolism of sugars, lipids and amino acids.
2.Vitamin B2 combines with specific proteins to produce yellow enzymes. Yellow enzymes play a role in the transfer of hydrogen in material metabolism and participate in the respiration process of tissues.
