1. In order for water to become a vapor, there must be sufficient heat energy to break its covalent bonds. 2. The most common monomer of carbohydrates is a molecule of amino acid. 3. Cholesterol is a saturated fat. 4. The enormous diversity of protein molecules is due mostly to the diversity of amino acid sequences within protein molecules. 5. The unique properties of each amino acid are determined by its particular R group.
