5. Energy in food comes from four macromolecules
Lipids
Proteins
Nucleic acids
Carbohydrates

6. Macromolecules are built from small pieces called monomers
Monomers come together to form polymers (broader term for macromolecules)

7. Protein monomer: amino acids
Protein polymer: protein, polypeptide
2 amino acids
Dipeptide + H2O
Peptide bond

H2O
Condensation

8. Amino acids join to form proteins
Draw, color, and label three amino acids, how they join together, and how they break apart in your notes.
Proteins can denature.

9. Carbohydrate monomer: monosaccharide
2 monosaccharides = disaccharide
Many monosaccharides = polysaccharide (polymer)

10. Monosaccharides join to form polysaccharides
