11. Vitamin and Minerals

Definition: "Small organic molecules present in diet which are required in small amounts”.
Most of the vitamins are not synthesized in the body and hence they must be supplied in the diet.
Structure
However, a few vitamins are synthesized in the body.
some are present as precursors.
The precursor forms of vitamins are called as provitamins.
In the body these provitamins are converted to vitamins.
