How do the vitamins differ from carbohydrates, fats, and proteins?
Structure. Vitamins are individual units; they are not linked together (as are molecules of glucose or amino acids).
Function. Vitamins do not yield energy when metabolized; many of them do, however, assist the enzymes that participate in the release of energy from carbohydrate, fat, and proteins.
Dietary intakes. The amounts of vitamins people ingest daily from foods and the amounts they require are measured in micrograms (?g) or milligrams (mg), rather than grams (g).
