Intestinal transport of vitamins.
Animals rely on acquiring through their diet, certain micronutrients required to support metabolism that we refer to as vitamins. The water-soluble vitamins are absorbed in the intestine only slowly by simple diffusion; specific mechanisms of transport have evolved that normally insure complete availability of each substrate to the organism. Secondary genetic errors that result in the impairment of an intestinal transport mechanism may become debilitating.
