Introduction:
Vitamin B6 (Vitamin B6), also known as pyridoxine, includes pyridoxine, pyridoxal, and pyridoxamine. It exists in the form of phosphate ester in the body and is a water-soluble vitamin. High temperature resistance. It was named vitamin B6 in 1936. Vitamin B6 is colorless crystal, easily soluble in water and ethanol, stable in acid solution, easily broken in alkaline solution, pyridoxine is heat resistant, pyridoxal and pyridoxamine are not resistant to high temperature. Vitamin B6 is more abundant in yeast, grains, meat, fish, eggs, beans and peanuts. Vitamin B6 is a component of certain coenzymes in the human body, and participates in various metabolic reactions, especially in close relationship with amino acid metabolism. Clinical application of vitamin B6 preparations to prevent pregnancy vomiting and radiation sickness vomiting.
Functions of Vitamin B6:
1. Participate in protein synthesis and catabolism, participate in all amino acid metabolism, such as heme metabolism, and tryptophan synthesis of niacin.
2. Participate in gluconeogenesis and UFA metabolism. It is related to the metabolism of glycogen, sphingomyelin and steroids.
3. Participate in the synthesis of certain nerve mediators (serotonin, taurine, dopamine, norepinephrine and γ-aminobutyric acid).
4. Metabolism of vitamin B6 and one carbon unit, vitamin B12 and folate, if they are metabolic disorders can cause megaloblastic anemia.
5. Participate in the synthesis of nucleic acids and DNA. Lack of DNA synthesis will be impaired. This process is very important for maintaining proper immune function.
6. The relationship between vitamin B6 and vitamin B2 is very close. Vitamin B6 deficiency is often accompanied by vitamin B2 symptoms.
7. Participate in the conversion of homocysteine to methionine, which has the effect of reducing chronic diseases. Mild hyperhomocysteinemia is considered as a possible risk factor for vascular disease. The intervention of vitamin B6 can reduce plasma homocysteine Cystine content.
