A. What is a vitamins?
 Prevent certain disease
 Have to get from our food(not synthesized in body),
 needed for enzymatic processes (must be organic and not energy producing)
 don’t need in mass quantities
 To be classified as a vitamin, a compound has to meet several criteria:
 It must be an organic dietary substance that is not energy
producing, as are carbohydrate, fat, and protein.
 It is needed in very small quantities to perform a particular
metabolic function and prevent an identified deficiency disease.
 It cannot be synthesized by the body, so it must be supplied in

 K:
 Functions: blood clotting, bone health,
 Found: dark green veggies :broccoli, spinach, Brussel sprouts
 Deficiencies: hemorrhage, lack of blood clotting, if on Coumadin
