1. Review of Organic Macromolecules How Structure Meets Function

2. Question of the day: Do Nutrition Facts Lie?

3. Structure of Macromolecules Monomers Polymers To build: dehydration synthesis To break: hydrolysis

4. Dehydration or Hydrolysis?

5. Nucleic Acid Monomer Nucleotide – 5 carbon sugar – Phosphate group – Nitrogen base

6. Protein Monomer Amino Acid – 20 types – R group varies

7. Carbohydrate Monomers Monosaccharides – Glucose – Fructose – Galactose C 6 H 12 O 6

8. Lipid Monomers and Polymers Triglyceride – 3 fatty acids – 1 glycerol

9. Nucleotide Function Transmits hereditary information by providing the codes to make proteins.

10. Protein Function Proteins have very specific shapes which allow for specific functions in living things: – Transport of O 2 – Defense against infections – Structure of hair, bones – Movement (muscles) – Chemical reactions (enzymes)

11. Function of Carbohydrates Polysaccharides – Glycogen- Energy storage in animals – Starch- Energy storage in plants – Cellulose- Cell wall structure in plants

12. Function of Lipids A certain type of lipid called a phospholipid forms the cell membrane.

13. Structure Meets Function Nucleic Acids— DNA’s double helix shape allows it easily to be copied

14. Structure Meets Function Proteins—Protein must have a proper shape in order to work. Ex. Sickle cell hemoglobin vs. Normal Hemoglobin

15. Carbohydrate Structure Meets Function We can digest starch but we cannot digest cellulose because of the way they are shaped.

16. Lipid Structure Meets Function Saturated Fats—single bonds; solid; bad Unsaturated fats—double bonds; liquids; good

17. Other test topics… Structure of an atom and its relationship to the function of bonding. Structure of water and water’s important functions (properties)
