1. 3.2 food Introduction to 3.2.1

2. Which type of food provides the most energy?

3. What are the four macromolecules?
Proteins
Carbohydrates
Lipids
Nucleic Acids

4. Monomers & Polymers
In the molecular world, the small subunits that ultimately link together to form larger molecules are called monomers, which literally means "single unit" (mono = one). When a bunch of monomers join together into a much larger molecule, they form a polymer, meaning "many units" (poly = many).

5. What are the Monomers?
Proteins = amino acids

6. Monomer
Nucleic Acid = Nucleotide

7. Monomer
Carbohydrate = monosaccharide

8. Monomer
Lipids – no monomer

9. Foods
Name two for each macromolecule.

10. Hydrolysis Hydrolysis literally means reaction with water.
It is a chemical process in which a molecule is cleaved into two parts by the addition of a molecule of water.
