UNIT 4 - MICRO NUTRIENTS (Vitamins)

What are Vitamins?

• Organic molecules with a wide variety of functions
• Cofactors for enzymatic reactions
• Essential, supplied in the diet
• Two distinct types: Fat soluble (A, D, E, K)
• Water soluble (B – complex, C)

Vitamins are organic molecules that are essential for normal  health and growth. They are required in trace amounts and must  be obtained from the diet because they are not synthesized in the  body. Before vitamins were discovered, it was known that lime  juice prevented the disease scurvy in sailors and that cod liver oil  could prevent rickets. In 1912, scientists found that, in addition to  carbohydrates, fats, and proteins, certain other factors called  vitamins must be obtained from the diet.
