Vitamin B12 is the only vitamin which contains metal ion (trivalent cobalt). Cobalamin is sometimes defined as the synonym of Vitamin B12, although they are not same compound but closely related compounds to fulfill folic acid role. Vitamin B12 is typically any substituted cobalamin derivative having similar biological activity. Hydroxocobalamin (abbreviated OHCbl), a cobalamin derivative in which the substituent is a hydroxyl group, is called vitamin B12b Vitamin B12 is a water soluble with a key role in the normal functioning of the and , and for the formation of . It is one of the eight . It is normally involved in the of every of the body, especially affecting synthesis and regulation, but also synthesis and energy production. Vitamin B12 is the name for a class of chemically-related compounds, all of which have vitamin activity. It is structurally the most complicated vitamin. of the basic structure of the vitamin can only be accomplished by , but conversion between different forms of the vitamin can be accomplished in the human body. A common synthetic form of the vitamin, , does not occur in nature, but is used in many pharmaceuticals, supplements and as food additive, due to its stability and lower cost. In the body it is converted to the physiological forms, and , leaving behind the , albeit in minimal concentration. More recently, , methylcobalamin and, adenosylcobalamin can also be found in more expensive pharmacological products and food supplements. The utility of these is presently debated. Historically, vitamin B12 was discovered from its relationship to the disease , which is an autoimmune disease that destroys parietal cells in the stomach that secrete intrinsic factor. Intrinsic factor is crucial for the normal absorption of B12, therefore, a lack of intrinsic factor, as seen in pernicious anemia, causes a vitamin B12 deficiency. Many other subtler kinds of , and their biochemical effects, have since been elucidated. We can supply VB12, it can be used in food, feed grade, pharmacial based on different types. Types: A) Vitamin B12 water-soluble, feed grade ---Specification: GB9841-88 and exporting standard ---Assay: 1%, 0.1%, 10%, --Carrier: mannitol, lactose ---Character: pale red powder, soluble in water --Function: it is able to part in the metabolism of one-charcoal-gene, to facilitate hematopoiesis, to treat pernicious anemia, to facilitate the growth of young poultry, and can be used as notorious feed additive for livestock and poultry Packing: 1kg/aluminum foil bag, 20kg/carton, 25kg/drum B) Vitamin B12, feed grade --- Specification: GB9841-88 & corporation standard & export ---Assay: 0.1%, 1%, 10% --Carrier: corn starch, calcium carbonate, Di-calcium phosphate ---Character: pale red powder, hygroscopic --Precaution: 1. Growth retardation, low transformed efficiency of feed. Pellagra, infectious dermatitis, poor fledging 2. It can adjust nervous system, improve hematopoietic function of the body, treat anemia and protect the liver 3. It is effective to treat fatty liver, hepatic necrosis, and especially effective to hepatic damage due to long-term use of antibiotics. 4. Low rate of incubation, high rate of dead embryos. Beeding difficulty of sows, disturbance in the grow of hind legs of piglets. It can meet the need for VB12 of fish and shrimp, prevent from deficiency in VB12 and from irritability, improve, immunocompetence, facilitate the transformation of nutrient in feed, and improve growth rate, survival rate and reproduction rate. Packing: 1kg/aluminum foil bag, 20kg/carton, 25kg/drum C) Vitamin B12, food additive ---Specs: Corporation Standard & Export Standard ---Assay: 0.1% 1% 2% ---Carrier: corn starch, mannitol, lactose, Di-calcium phosphate ---Character: pale red powder, hygroscopic Packing: 1kg/aluminum foil bag, 20kg/carton, 25kg/drum D) Mecobalamin JPXIV --Appearance: Dark red crystals or crystalline powder; slightly soluble in water or ethanol, and practically insoluble in acetonitrile, affected by light --Precaution: peripheral neuropathies (diabetic and alcoholic neuropathy, drug induced neuropathy, lumbago, intercostals neuralgia and diabetic retinopathy, entrapment neuropathy and other neuropathies Packing: 1,000g/tin, 500g/tin, or 100g/tin E) Cyanocobalamin CP2005 BP2002 USP28 --Appearance: Crimson crystals or crystalline powder, flavorless and tasteless. Gradually hygroscopicity. Easily decomposed when exposed to light. Slightly soluble in water or ethanol. Insoluble in acetone, chloroform and ether. --Function: mealoblasticanemia, malnutrition, psothemorrhagicanemia, neuralgia and disturbance Packing: 1,000g/tin, 500g/tin, or 100g/tin F) Cobamamide: CP2005 ---Description: Crimson crystals or crystalline powder, flavorless and tasteless, strong hygroscope city. Easily decomposed when exposed to light. Easily soluble in weather, insoluble in ethanol. Hardly soluble in acetone, ether and chloroform. --Function: high activity in the form of coenzyme. Ordinary VB12 has to be transformed by liver before digested and utilized. Packing: 1,000g/tin, 500g/tin, or 100g/tin G) Hydroxocobalamin: BP2002 --Description: Crimson crystals or crystalline powder, flavorless and tasteless. Gradually decomposed when heated (100°C) --Function: Similar to VB12. Its concern traction in blood after injection is higher than that of VB12 with the same dosage. It has slow exaction with urine and has long-term effect. Effective to pernicious anemia and other diseases caused by deficiency in VB12.If used in large dosage, it can act as antidote against cyanide and transform it into cyanocobalamin
