Information
Vitamins have diverse biochemical functions. Some have hormone-like functions as regulators of mineral metabolism ( e.g. vitamin D) , or regulators of cell and tissue growth and differentiation ( e.g. some forms of vitamin A) . Others function as antioxidants ( e.g. vitamin E and sometimes vitamin C) . The largest number of vitamins ( e.g. B complex vitamins) function as precursors for enzyme cofactors, that help enzymes in their work as catalysts in metabolism. In this role, vitamins may be tightly bound toenzymes as part of prosthetic groups: for example, biotin is part of enzymes involved in making fatty acids. Alternately, vitamins may also be less tightly bound to enzyme catalysts as coenzymes, detachable molecules which function to carry chemical groups or electrons between molecules. For example, folic acid carries various forms of carbon group – methyl, formyl and methylene - in the cell. Although these roles in assisting enzyme-substrate reactions are vitamins' best-known function, the other vitamin functions are equally important.
