Vitamin B12, which is called VB12 for short, also known as cobalamin, and is one of the B vitamins, is a class of complex organic compounds containing cobalt Corrin class ,and contained trivalent cobalt in similar porphyrin Corrin plane at the center of the ring.It is the largest and most complex vitamin molecule that has been discovered. It is also the only vitamin with metal ion. The crystal is red, it is also called red vitamin.The plant does not contain VB12, and can not produce VB12. The liver is the best source of VB12, then from milk, meat, eggs, fish and so on.VB12 is an essential coenzyme in the synthesis of RNA and DNA. The lack of VB12 in vivo can cause pathological changes in the nervous system such as peripheral nerve and central nervous system.
1. Vitamin B12 deficiency can cause anemia, nervous system disorders. It can be used in infant foods, used amount is 10~30μg/kg; use in strengthening drink liquid and the amount is 2~6μg/kg.
2. Mainly used to treat megaloblastic anemia, poor nutrition, blood loss anemia, neuralgia and obstructive disorders.
3. As the feed nutrition fortifier, with anti-anemia effects of pernicious anemia, nutritional anemia, parasites and anemia and effective dosage is 15-30mg/t.
4. Vitamin B12 is essential for the metabolism of the human body. The average total amount of vitamin B12 in the human body is 2-5mg, 50-90% of which is stored in the liver, the body needs to release into the blood in the formation of red blood cells. Chronic lack of B12 can cause pernicious anemia. B12 and folic acid are important fear of enzymes during cell nucleic acid synthesis, involved in the synthesis of purines, pyrimidines, nucleic acids and methionine; and allows methyltransferase to promote the synthesis of the base; at the same time to increase the synthesis of sugar yuan, thus eliminating the role of liver fat. Clinical often as a drug for the treatment of liver diseases. Human need vitamin B121 micrograms per day, every day foods provide 2 micrograms, to ensure the normal needs. Hydroxocobalamin in Vitamin B12 reacts with cyanide to generate Vitamin B12, to eliminate cyanide toxicity. Therefore, the lack of vitamin B12 for cyanide sensitivity is higher than the average person. Thus, vitamin B12 deficiency sensitivity to cyanide higher than the average person. Vitamin B12 is mainly used to treat pernicious anemia, megaloblastic anemia, antifolate drugs starting from anemia and multiple neuritis.
