Introduction
Vitamin B12 is also called the cobalt amine or cyanide cobalt element. It is a kind of composed of porphyrin compounds containing cobalt B vitamins. Initially found taking the liver can control the symptoms of pernicious anemia, after 20 years of research, was isolated from the liver until 1948 a control effect of pernicious anemia with red crystal material, named as vitamin B12. In 1963, determine its structural formula. To complete the synthetic in 1973. Vitamin B12 is found so far in B vitamins at the latest one. Vitamin B12 is a kind of cobalt containing 3 price polycyclic compounds, 4 reduction of pyrrole ring together into a goo Lin large ring (similar to porphyrin), is the core of vitamin B12 molecules. So are the class of compounds containing this kind of ring goo moiety. Vitamin B12 for shallow red needle crystal, soluble in water and ethanol, at pH 4.5 ~ 5.0 under the condition of weak acid is the most stable, strong acid (pH < 2) or break down in the alkaline solution, when it is heated to a certain degree damage, loss of high temperature disinfection is small, but a short time in bright light, or in addition line.

Application
1.Manner to promote the development of red blood cells and mature, make the body hematopoiesis function in normal state, the prevention of pernicious anemia;
2.To maintain a healthy nervous system This exists in the form of coenzyme, can increase the utilization rate of folic acid, promote the metabolism of carbohydrate, fat and protein;
3. Have the function of the activation of amino acids and promote the biosynthesis of nucleic acid, can promote protein synthesis, its important role in the growth and development of infants.
4.The metabolism of fatty acids, fat, carbohydrate, protein, is the proper use of body;
5.eliminate fidgety, focus attention, enhance memory, and a sense of balance.
6.It is indispensable to the nervous system function and improve the vitamin, participate in the formation of nerve tissue, a lipoprotein, One is to improve the utilization rate of folic acid,.
7.with folic acid synthesis of methionine by homocysteine (synthesis) and choline, produced in the process of purines and pyrimidines synthetic cyanocobalamin ShenJi cobalt precursor substances such as methyl amine and coenzyme B12, involved in many important compounds.
