What is Vitamin B12?

Vitamin b12 powder is a general term for vitamin B chemical substances with a cobalaline ring structure. Since the first discovered cyanocobalamin is ranked 12th according to the name of the vitamin, and it is generally used to call cyanocobalamin as vitamin B12.

In fact, there are four vitamin B12 families: cyanocobalamin, hydroxycobalamin, adenosylcobalamin and methylcobalamin. The latter three are all drugs with a chemical structure similar to cyanocobalamin.

The chemical structure of the vitamin family is that the four pyrrole rings are connected in a bridging manner, and the center is complexed with a 6-valent cobalt ion. The different functional groups connected to the 13 position are different cobalamins, and the cyanide is connected to cyanide. Cobalamin, which is connected to methyl group to form methylcobalamin, to hydroxyl group to form hydroxycobalamin, and to adenosyl group to form adenosylcobalamin

Among them, methylcobalamin and adenosylcobalamin have direct biological activity and can directly participate in biochemical reactions in the body; while cyanocobalamin and hydroxycobalamin have no direct biological activity and need to be converted into methylcobalamin and adenosylcobalamin. Exert biological activity.

The main functions of vitamin B12 in the body are:

1. Promote methyl transfer, promote the development and maturation of red blood cells, keep the human hematopoietic function in a normal state, and prevent pernicious anemia;

2. Maintain nervous system health;

3. Vitamin b12 powder exists in the form of coenzyme, which can increase the utilization rate of folic acid and promote the metabolism of carbohydrates, fats and proteins.

Methylcobalamin mainly found in blood and other body fluids, it belongs to the methylation active preparation of endogenous coenzyme B12. It can be directly used by the body without going through absorption and metabolism. It participates in the methyl conversion of substances and is easily transported to nerve cells. Sub-microstructures (such as nuclei, mitochondria, ribosomes, etc.) promote the synthesis of nucleic acids, proteins and lipids in nerve cells.

In addition, it is a coenzyme of methionine synthetase and is involved in methionine-homocysteine metabolism.

Therefore, its two main drug effects are to reduce homocysteine and peripheral neuralgia. Vitamin b12 is considered to be a safe and effective drug for the treatment of peripheral nervous system diseases. The daily dose: is 0.5 to 1.5 mg.
