Vitamins

The Vitamins are necessary auxiliaries in metabolism. They combine with specific proteins, as parts of various oxidative enzyme systems which are concerned with the breakdown of carbohydrates, proteins, and fat in the body. Thus, they are intimately involved in the mechanism which releases energy, carbon dioxide and water as the end products of metabolism.

Vitamins can be broadly divided into Fat Soluble and Water Soluble Vitamins. Vitamins A D E and K are fat-soluble vitamins. Vitamins B ( B1 B2 B6 B12 ) and C are water-soluble.
