A derivative of this molecule serves as a cofactor for the methyl-malonyl-Coenzyme A mutase, and it is also needed for the action of the methyl-transferase that converts homocysteine to methionine. The inactivity of that enzyme leads to a thymine shortage, which is the cause of problems associated with deficiencies in this molecule. It can only be absorbed through cubulin receptors in the terminal ileum while bound to a product of parietal cells known as intrinsic factor. For 10 points, name this vitamin needed to prevent pernicious anemia, which is also called cyano-cobalamin thanks to its central cobalt atom.
