Vitamins are organic compounds required as nutrients in organisms. They are essential to normal metabolism. Organisms do not synthesize sufficient amounts of vitamins and must obtain them through their diet. Vitamins are classified by their biological and chemical activity, not their structure. Thus, each vitamin refers to a number of vitamer compounds that all show the biological activity associated with a particular vitamin family. Vitamins have diverse biochemical functions. Some vitamins, like vitamin D, have hormone-like functions as regulators of mineral metabolism while others, like vitamin E, function as antioxidants. Others still, like members of the B family of vitamins function as precursors for enzyme cofactors that help enzymes work as catalysts in metabolism. Alfa Aesar supplies the compounds that are vitamins in humans in several grades and purities.
