What is Vitamin B2 ?


Vitamin B2, also known as riboflavin, is one of the B vitamins, 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 the role of hydrogen transfer in biological redox). When it is lacking, it will affect the biological oxidation of the body and cause metabolic obstacles.


The storage of vitamin B2 in the body is very limited, so it must be provided by the diet every day. Two properties of vitamin B2 are responsible for its loss:


(1) Can be destroyed by light;

(2) It can be destroyed by heating in alkaline solution.


Benefits of Vitamin B2 Riboflavin

vb2

Most dietary vitamin B2 is present in the form of flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) coenzymes bound to proteins. After entering the stomach, under the action of gastric acid, it is separated from protein, converted into free vitamin B2 in the upper digestive tract, and absorbed in the upper part of the small intestine.


1. Participate in biological oxidation and energy metabolism in the body, and it is related to the metabolism of carbohydrates, proteins, nucleic acids and fats. It can improve the utilization rate of proteins in the body, promote growth and development, and maintain the integrity of skin and cell membranes. It has the function of protecting the skin, hair follicles, mucous membranes and sebaceous glands.


2. Participate in the growth and metabolism of cells, and are essential nutrients for the metabolism and repair of body tissues, such as strengthening liver function and regulating the secretion of adrenaline.


3. Participate in the metabolism of vitamin B6 and niacin, which is a model of the coordination effect of B vitamins. As prosthetic groups, FAD and FMN are involved in the conversion of tryptophan to niacin, and the conversion of vitamin B6 to pyridoxal phosphate.


4. It is related to the absorption, storage and mobilization of iron in the body.


5. It also has antioxidant activity, which may be related to flavinase-glutathione reductase.

Identification

Fluorescence experiment

The 1% (mg / ml) aqueous solution is pale yellow-green under transmitted light and has strong yellow-green fluorescence. Add dilute hydrochloric acid solution to disappear fluorescence or add a little sodium hydroxide solution to fluorescence disappear; add a little sodium dithionite, shake it, the yellow fades and the fluorescence disappears.
