Answer to Question 1

The vitamins differ from carbohydrates, fats, and proteins in the following ways:
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 carbohydrates, fats, and proteins.
Food contents. The amounts of vitamins people ingest from foods and the amounts they require daily are measured in micrograms (g) or milligrams (mg), rather than grams (g).
