1. Lipids
Warm up! What do you already know about lipids? Name 3 foods that are high in lipid (ex: fat)
What would you like to learn about lipids?

2. Lipids Fats, oils, waxes Functions: Made of: Long-term energy storage
Cell membrane
Waterproofing
Made of:
C, H, O

3. Lipid Building Blocks
Most lipids are composed of three fatty acids bonded to a glycerol molecule
This is also known as a triglyceride…see following slides!

4. LIPID

5. Check Point Questions!
How is the chemical structure of lipids different from carbs and proteins?
What are the functions of lipids?

7. Types of Lipids SATURATED Fats Examples: butter, lard
Fatty acids are full of hydrogen
No double bonds between C
Examples: butter, lard
Solid at room temperature
Considered “unhealthy” fats

8. Ex: olive oil, vegetable oil
UNSATURATED Fats
Double bonds
Not “full” of hydrogen
Liquid at room temperature
Ex: olive oil, vegetable oil
Usually liquid
Considered “good” fats

9. Trans fats Man made in a lab
Unsaturated, but solid at room temperature
Ex: margarine
Now known to be unhealthy

10. Cholesterol

11. Check Point Questions!
What’s the difference between saturated and unsaturated fats?
What are trans fats?
