Vitamin B12

Vitamin B12, or Cobalamin, is one of the eight B vitamins. It is expected to guarantee the best possible working and soundness of nerve tissue, cerebrum capacity, and red platelets. Like all B vitamins, vitamin B12 is a water-solvent vitamin. This implies it breaks up in water and goes through the circulation system. The human body does not store cobalamin. Any overabundance or undesirable sums are discharged through urine. Basically, vitamin B12 is the most complex vitamin. It is also the biggest. Cobalamin must be modernly created through bacterial aging combination.

By helping the human body to ingest folic corrosive, it encourages the arrival of vitality.

Vitamin B12 Bacteria

Vitamin B12 Bacteria

Many say that animal-derived foods are ones that contain vitamin B12. Actually, no foods naturally contain vitamin B12 - neither animal or plant foods. Vitamin B12 is a kind of bacteria. This bacterium is created from invisible microorganisms. Vitamin B12 is the only vitamin that contains a trace element - cobalt - which gives this vitamin its chemical name - cobalamin - which is pointed in the mid of molecular structure. Humans and all vertebrates require cobalt, although it is assimilated only in the form of vitamin B12.

Vitamin B12 also called cobalamin, and a water-soluble vitamin which takes part in functioning the brain, nervous system, and the formation of red blood cells. It is one of eight B vitamins. It is the main cause to metabolize each and every cell of the body, especially affecting DNA synthesis, fatty acid, and amino acid metabolism. No fungi, plants, nor animals (including humans) are capable of producing vitamin B12. Proved sources of B12 are animal products (meat, fish, and dairy products) and supplements. Certain researchers have identified that non-animal products are one of the natural sources of vitamin B12. Vitamin B12 is the largest and most structurally complicated vitamin and can be produced industrially only through a bacterial fermentation-synthesis. Fortified foods are mainly made up with vitamin B12 elements and therefore it’s sold as a dietary supplement.

Vitamin B12 Bacteria

Vitamin B12 consists of a class of chemically related compounds (vitamins), all of which show pharmacological activity. It consists an ingredient called biochemically (chemical symbol Co) positioned in the center corrin ring. The vitamin is created as hydroxocobalamin with a microorganism.

B12 synthesis is known to occur naturally in small intestines particularly in the ileum, which is considered as the primary site of B12. Some people argues that vitamin B12 is present in the mouth as well and intestines. Furthermore, Active Vitamin B12 coenzymes are found in bacteria in the mouth, around the teeth, in the nasopharynx, around the tonsils, and in the tonsillar crypts, in the folds at the base of tongue, and on the upper bronchial tree. Absorption of the natural B12 coenzymes can take place in the mouth, throat, esophagus, bronchial tubes and even in the upper small intestines, along the intestinal tract. This does not involve the complex enzyme mechanism for absorption (Intrinsic Factor) in the small intestine as required by cyanocobalamin. The coenzymes are absorbed by diffusion from mucous membranes.

External B12 coming into the body must be combined with a mucoprotein enzyme named Intrinsic Factor, which is present in gastric secretions areas that are to be properly assimilated. If Intrinsically is impaired or absent, the B12 synthesis will not take place, no matter how much it is available in the diet. A B12 deficiency can raise from antibiotics from the drugs and alcohol. So a huge amount of B12 is required to drug users.

Function and Process of B12 in our Body

Actually, Vitamin B12 helps us to keep build up healthy nerves and blood cells which in turn can make DNA, the genetic material in all cells. Additionally, it helps to avoid megaloblastic anemia which makes people weary.

Two steps are required for the body to absorb vitamin B12 from food. First, hydrochloric acid in the stomach separates vitamin B12 from the protein to which vitamin B12 is attached to food. After this, vitamin B12 combines with a protein made by the stomach called intrinsic factor and is absorbed by the body. Some suffer from pernicious anemia, in a terrible situation. As a result, they have trouble absorbing vitamin B12 from all foods and dietary supplements.
