What is the purpose and function of the vitamin B12?
Answers: Tony, I can get the drift how you want a basic description of Vitamin B12. What pious is it for someone to just copy and cement a description they found elsewhere?
Vitamin B12 is very impressive for DNA replication, normal audacity cell activity, tissue and cellular repair, and RBC (red blood cell) formation.
After this point, a 10 year weak might not understand, but explicitly only because the words are rather long. If you get bygone that point, I have broken everything down, and provided you near a lot of links for further research.
You asked more or less functions of Vitamin B12, as in, what their effect is on the body. There are two enzymes that require Vitamin B12 to complete. One ismethylmalonyl Coenzyme A mutase and the other is 5-methyltetrahydrofolate-homocysteine methyltransferase. An enzyme is a protein that accelerates a chemical recoil. So, these are functions of Vitamin B12 because they are two things that are dependent on Vitamin B12 that produce changes within chemical reactions.
Methylmalonyl Coenzyme A mutase is an enzyme involved contained by key metabolic pathway. A metabolic pathway is a series of chemical reactions occurring inwardly the cell. So basically, methylcobalamin is directly involved near metabolism.
5-deoxyadenosyl cobalamin is an enzyme that is responsible for producing methione. What is methione? Methione is an amino sour, which is a building block of protein.
Good luck!
Vitamin B12 is a vitamin cofactor in metabolism. In summary, B12 is used within the synthesis of myelin on nerves and DNA affecting red cells predominantly. It's defect causes retiring sytem disease and anemia.
Coenzyme B-12 participates within two types of enzyme-catalyzed reactions.
1. Rearrangements contained by which a hydrogen atom is directly transferred between two adjacent atoms.
2. Methyl (-CH3) group transfers between two molecules.
In humans, merely two coenzyme B-12-dependent enzymes are known:
1. Methylmalonyl Coenzyme A mutase (MUT) is an enzyme that uses B12 surrounded by an important step surrounded by the extraction of energy from proteins and fat. Loss of this ability from B12 defect results in an increased methylmalonic acerbic (MMA) level. This step is vital for myelin synthesis and certain other functions of the interior nervous system.
In a vitamin B12-dependent antipathy, methionine is subsequently converted to S-adenosyl-methionine (SAM), which is necessary for methylation of myelin sheath phospholipids.
In a second criticism, B-12 is used to convert methylmalonyl coenzyme A into succinyl coenzyme A. Failure of this second reaction to take place results in elevated level of methylmalonic acid. Excessive methylmalonic sharp will prevent normal fatty bitter synthesis, or it will be incorporated into fatty acid itself a bit than normal malonic tart. If this abnormal fatty acerbic subsequently is incorporated into myelin or if the methylation of the myelin sheath phospholipids fails to come about, the resulting myelin will be too fragile, and demyelination will occur. The result is disease of the interior nervous system and spinal cord.
2. A second enzyme uses B12 to catalyze the conversion of the amino tart Hcy into Met (for more see MTR's reaction mechanism). This functionality is lost surrounded by vitamin B-12 deficiency, and can be measured clinically as an increased homocysteine smooth. B-12 also helps to regenerate folic sharp, and thus decrease the obligation for it in the diet. This results contained by problems with DNA synthesis, and ultimately within ineffective production of blood cells, and also within intestinal wall cells which are responsible for incorporation, in the once-dreaded and deadly disease, pernicious anemia.
body don't get adequate iron so they give you b12 to build it up
