1. Characteristics of Organic Molecules

2. Figure 4.2 The shapes of three simple organic molecules

3. Figure 4.4 Variations in carbon skeletons

4. Figure 4.4x Hydrocarbons: molecular models Butane Isobutane Hexane Cyclohexane

5. Figure 4.5 The role of hydrocarbons in fats

6. Figure 4.6 Three types of isomers Different structures can be built from the same molecular formula.

7. Shape matters! Simply having the same molecular formula does not make molecules the same. The arrangement of atoms and placement of functional groups can dramatically change function.

8. Figure 4.6ax Structural isomers

9. Figure 4.7 The pharmacological importance of enantiomers

10. Figure 4.8 A comparison of functional groups of female (estradiol) and male (testosterone) sex hormones Functional Groups give molecules distinctive properties.

11. Six functional groups are important in the chemistry of life Hydroxyl Carbonyl Carboxyl Amino Sulfhydryl Phosphate

12. Five of the big 6 groups – which was not in your book?

13. Phosphate group: O O P OH OH Critical for moving energy from molecule to molecule
