Study Notes
Vitamins
- Vitamins are organic compounds vital for many biochemical processes
- Many vitamins function as coenzymes
- Vitamins are not incorporated into tissues or oxidized by them
- Vitamins are required in very small amounts
Provitamins
- Precursors of vitamins that the body converts into active vitamins
- Examples include carotenoids, which are provitamin A
Vitamers
- Different forms of the same vitamin
- Example: Vitamin D has two vitamers, D2 and D3
Vitamin Classification
- Classified primarily as fat-soluble or water-soluble, based on their solubility in either fat or water
- Fat-soluble vitamins include A, D, E, and K
- Water-soluble vitamins include the B complex and C vitamins
- Fat-soluble vitamins are stored in the body's fatty tissues, while water-soluble vitamins are easily transported and eliminated
