Vitamin B2 powder, also known as riboflavin, its chemical structure is a derivative of isoalloxazine with a ribose side chain. Vitamin B2 powder is an orange-yellow crystal with a bitter taste and poor water solubility, and the aqueous solution exhibits yellow-green fluorescence. It is insoluble in organic solvents, stable in acidic solutions, and can withstand short-term high-pressure heating, but it is easily destroyed when heated in alkaline solutions.
Active daim ntawv ntawm vitamin B2
Vitamin B2 is absorbed in the upper part of the small intestine, and after absorption, it is phosphorylated in the intestinal wall, partly in the liver and blood, and forms two coenzymes in the form of phosphate ester in the tissue. One coenzyme is flavin mononucleotide (FMN) and the other is flavin adenine dinucleotide (FAD). FMN is produced by vitamin B2 and ATP catalyzed by flavin kinase, and FAD is produced by FMN and ATP catalyzed by flavin nucleotide pyrophosphoesterase. Both coenzymes FMN and FAD are combined with enzyme proteins called flavoproteins, also known as flavoenzymes.
Nyob rau hauv xyoo tas los no, kev siv cov vitamin B2 tau pom tshiab. Nws muaj cov haujlwm ntawm diuresis, detumescence, tiv thaiv kab mob qog noj ntshav, kho cov dej daj thiab kab mob hyperischemic globin. Nws muaj qhov tseem ceeb los tiv thaiv -platelet aggregation (PAT) thiab tiv thaiv ischemic myocardium cuam tshuam rau mob myocardial infarction, tsiaj qauv.
Ntxiv cov vitamin B2
Vitamin B2 is widely distributed in all leafy vegetables, warm-blooded animal or fish meat, and cereals are also a source of vitamin B2. The intestinal bacteria of many animals can synthesize riboflavin, but the amount of human intestinal synthesis is not enough to meet the needs of the whole body. Vitamin B2 is the prosthetic group of yellow enzymes in the body and participates in the body's energy and protein metabolism. When vitamin B2 is deficient, the damaged parts of skin friction cannot be repaired, so diseases such as angular stomatitis, glossitis, ophthalmia, and scrotum will occur.
