Physiological function
1. Improve the utilization of folic acid, synthesize methionine (synthesized from homocysteine) and choline together with folic acid, and synthesize cyanocobalamin precursors such as methylcobalamin and coenzyme during the process of producing purines and pyrimidines B12, involved in the methylation process of many important compounds. When vitamin B12 is deficient, the activity of transferring methyl groups from methyltetrahydrofolate is reduced, making folic acid into an unusable form, leading to folic acid deficiency.
2. Maintain the metabolism and function of nerve myelin sheath. When vitamin B12 is lacking, it can cause neurological disorders, spinal cord degeneration, and Chemicalbook can cause severe psychiatric symptoms. Vitamin B12 deficiency can cause peripheral neuritis. The early manifestations of a child's vitamin B12 deficiency are abnormal mood, sluggish expression, unresponsiveness, and finally anemia.
3. Promote the development and maturation of red blood cells. Methylmalonyl-CoA is converted into succinyl-CoA, which participates in the tricarboxylic acid cycle, and succinyl-CoA is related to the synthesis of heme.
