Factory Supply Raw Material Vitamin B12 Methylcobalamin CAS:68-19-9 Vitamin B12 powder

Product Description

 

Vitamin B12 is also known as cobalamin or cobalt cyanide. It is a porphyrin compound containing a cobalt B vitamin. It was first discovered that taking the liver can control the symptoms of pernicious anemia. After more than 20 years of research, it was isolated from the liver until the control effect of a pernicious anemia in 1948 was red crystal, named vitamin B12. In 1963, its structural formula was determined. The synthesis was completed in 1973. Vitamin B12 has recently been found in B vitamins. Vitamin B12 is a polycyclic compound containing trivalent cobalt, and the four reduced pyrrole rings form a viscous macrocycle (similar to a porphyrin), which is the core of the vitamin B12 molecule. The same is true for compounds containing such a cyclic moiety. Vitamin B12 is light red needle-like crystal, soluble in water and ethanol. It is most stable under mild acid conditions at pH 4.5~5.0, strong acid (pH <2) or decomposed in alkaline solution when it is heated to a certain extent. The loss of high temperature sterilization is small, but under strong light for a short time, or on the line.

Function of Vitamin B12

1. Way to promote red blood cell development and maturation, so that the body's hematopoietic function is in a normal state, preventing pernicious anemia;

2. Maintaining a healthy nervous system in the form of a coenzyme that increases the utilization of folic acid and promotes the metabolism of carbohydrates, fats and proteins;

3. It has the function of activating amino acids and promoting nucleic acid biosynthesis, which can promote protein synthesis, which plays an important role in the growth and development of infants.

Fatty acid, fat, carbohydrate, protein metabolism, is the correct use of the body;

5. Eliminate irritability, focus attention, enhance memory and balance.

6. Nervous system function is indispensable, improve vitamins, participate in the formation of nerve tissue, a lipoprotein, first, improve the utilization of folic acid.

7. Synthesis of methionine by folic acid via homocysteine (synthesis) and choline, the magical cobalt precursors such as methylamine and coenzyme B12 produced during the synthesis of cyanocobalamin by purine and pyrimidine Many important compounds.
