    Rather than studying the complexity of cobalamins,chemists have found that the properties of cobalamins can be simulated using model compoundssuch as cobaloximes, where the ligands are two dimethylglyoximate substituents.3 One suchcobaloxime compound, Co[CH(CH3)2](dmgH)2(py) is explored in this experiment throughsynthesis and .   Vitamin B12 is a water-soluble vitamin that is naturally present in some foods, added to others, and available as a dietary supplement and a prescription medication. Vitamin B12 exists in several forms and contains the mineral cobalt [ ], so compounds with vitamin B12 activity are collectively called “cobalamins”.

    The book also ponders on the biosynthesis of pantothenic acid and coenzyme A and metabolism of biotin, analogues, folic acid, pteridine derivatives, and cobalamins. Discussions focus on the uses of radioactive cobalamins in metabolic studies, absorption of cobalamins, pteroylpolyglutamates, and biosynthesis of folate compounds, interconversions. metalloenzymes with radical intermediates (e.g., cobalamins, amine oxidases), Chapter 14 reviews the principal facets of metal ion receptors and signaling, including, of course, the multiple roles of nitric oxide in biological systems. The book also contains two outstanding tutorials on biochemistry and coordination.

    Few clinical trials of eye vitamins or supplements for glaucoma have been conducted. Some evidence suggests that a high intake of vitamin B through dietary sources, including green leafy vegetables, may reduce the risk of some types of glaucoma. But B complex supplements, including folic acid, vitamin B6 and vitamin B12, don't appear to offer.

Cobalamin (vitamin B12) was discovered in the first half of the 20th century. Vast amount of information on the role of the vitamins in human health and disease became available. Cobalamin science was, however, based on theoretical concepts that have been accepted without further proof of.

Cobalamin (B12) is a necessary cofactor for methionine synthase, the enzyme that transfers the methyl group from 5-MTHF to homocysteine using methyl-cobalamin as an intermediate. Vitamin B12 should be used when supplementing folates, especially folic acid.

While there are clinicians that prefer one form of B12 over another (cyanocobalamin, methylcobalamin.

The first page of the PDF of this article appears above.This text aims to demonstrate that it is not so much a lack of B12 that causes ill health, but that rather it is the modern western lifestyle that may generate excess requirements of this micronutrient.

In particular this text will look at the little known issue of mercury, and how it interferes with normal cobalamin metabolism.
