    http://www.ncbi.nlm.nih.gov/pubmed/1476405 Not sure how involved you are trying to get, but you can find abstracts & articles online at pubmed, just do a search on the vitamin/mineral and animal species and it will bring up any papers on the combo.

    5. Fate of minerals and vitamins
    Minerals and vitamins in the feed do not require separate digestion. The minerals and water soluble vitamins such as vitamin B complex and vitamin C are absorbed directly along with the water, from the walls of the small intestine. The fat soluble vitamins such
    as vitamin A, D, E, and K are associated with food fats and are absorbed along with them.

    Vitamins are organic molecules that are necessary for normal metabolism in animals, but either are not synthesized in the body or are synthesized in inadequate quantities. Consequently, vitamins must be obtained from the diet. Most vitamins function as coenzymes or cofactors. Deficiency states are recognized for all vitamins, and in many cases, excessive intake also leads to disease.

    http://academic.brooklyn.cuny.edu/biology/bio4fv/page/coenzy_.htm
    coenzymes are organic molecules that are required by certain enzymes to carry out catalysis. They bind to the active site of the enzyme and participate in catalysis but are not considered substrates of the reaction. coenzymes often function as intermediate carriers of electrons, specific atoms or functional groups that are transfered in the overall reaction. An example of this would be the role of NAD in the transfer of electrons in certain coupled oxidation reduction reactions.
