1. Organic Compounds!!
LIPIDS

2. What makes McDonald’s fries taste soooo good?

3. Lipids
Are made of C, H, O
Have a much greater ratio than 2:1 of hydrogen to oxygen
Found in cell membrane
Store energy in C – H bonds; longer lasting than carbohydrates
Fats:
Solids
oils **

4. Building Blocks of Lipids
Made of 2 parts: 3 Fatty Acids and 1 Glycerol
Glycerol - an alcohol - serves as backbone of the molecule
3 Fatty acids - Long hydrocarbon chains **

5. Can you identify this?
CH2(OH)CH(OH)CH2(OH)

6. This is a typical fat!
Glycerol
Can you locate the glycerol molecule and the 3 fatty acids, circle & label them!
Fatty Acids

8. Can you identify these?? Saturated: single bonds (from animal)
Unsaturated: double bonds (from plants)

9. Cell Membrane
Can you identify the lipids?
Hydrophobic/hydrophilic

10. GUESS??
Can you identify what this is???

11. Let’s Practice! Dehydration Synthesis of Lipids: Hydrolysis:
1 glycerol + 3 fatty acids  lipid +3 water
(remove water)
Hydrolysis:
Lipid + 3 water  1 glycerol + 3 fatty acids
(add water)

12. Dehydration Synthesis of Lipids!**

13. Hydrolysis of Lipids!

14. Review Can you identify the process ?
