Brief Introduction:

Vitamin B2, also known as riboflavin, the CAS number is 83-88-5, which is a type of B vitamin and is a water-soluble vitamin. It plays a variety of important physiological functions in the human body.

Vitamin B2 participates in the catalytic reactions of various enzymes in the body and helps maintain the normal energy metabolism of cells. It is a component of two important coenzymes, FAD (Flavin Adenine Dinucleotide) and FMN (Flavin Mononucleotide). These two coenzymes participate in a variety of redox reactions in the body to convert carbohydrates, fats and proteins in food into energy.

In addition, Vitamin B2 is also involved in the synthesis of other vitamins and amino acids, regulates growth and development, maintains normal visual function and skin health, and is also important for maintaining the normal function of mucous membranes and eyes.
