Physical and chemical properties:

Water-soluble vitamins, but slightly soluble in water, at 27.5 ℃, the solubility of 12mg / 100mL. Soluble in sodium chloride solution, soluble in dilute sodium hydroxide solution, easy to dissolve in alkaline solution, stable in strong acid solution. Heat resistance, oxidation resistance. Light and ultraviolet radiation cause irreversible decomposition.

The main physiological function of vitamin B2 is to promote metabolism as a coenzyme. Riboflavin and phosphate and a molecule of protein combined into lutein. This type of enzyme, also known as dehydrogenase, it is important to be very important to transfer hydrogen atoms to sugar, lipid and amino acid metabolism are important. It is essential for many animals and microbial growth.

Vitamin B2 binds to a specific protein to form a yellow enzyme. Yellow enzyme in the material metabolism from the role of hydrogen, involved in the organization's breathing process.
