1. Lipids  Commonly known as:  Fats  Oils  Waxes

2. 10/14/20152  1. Organic Compound  Made up of carbon  Feels waxy or oily to the touch

3. 10/14/20153 d.Protects our major organs Function of a lipid: a.Stores energy ~ long term b. Main component of our cell membranes c. Insulates our body

4. 10/14/20154 Lipids are made up of: C, H and O Same set of elements found in carbs ……unused carbs get stored as body fat.

5. 10/14/20155 Like carbohydrates and proteins, lipids are made up of repeating units. The repeating units in lipids are called: -Triglycerides “3”

6. 10/14/20156 Many bonds need to be broken -need to add: water and enzymes “lipase” H2OH2O Lipds are then broken down by the process “Hydrolysis”

7. 10/14/20157 Lipids contain more energy per gram than any other food source…very calorie loaded

8. 10/14/20158 Types of lipids: 1.FATS a. Are solid at room temperature b. Found in animal products Lard Butter Meat Egg yolks Milk

9. 10/14/20159 c. Known as “saturated” fats -unhealthy because they contain: -heart unhealthy “cholesterol”

10. 10/14/201510 2. OILS a.Normally liquid at room temperature b.Found in plant products Margarine Vegetable Oils Nuts Olives

11. 10/14/201511 c.Known as “unsaturated” fats/lipids -contains same amount of calories as saturated but are more healthier for you because they do not contain cholesterol.

12. 10/14/201512

13. 10/14/201513 3.Waxes a. Found in plants and animals b. Form of protection -covers all major organs c. Waterproof structures Cuticle on leaves Earwax

14. 10/14/201514 4.Phospholipids a. Used to create our cell membranes.

15. 10/14/201515 Two test for the presence of lipids: 1. Brown Bag Test -leaves a translucent spot -light passes through it

16. 10/14/201516 Yummy!!!!!!!

17. 10/14/201517 2. Solubility Test -lipids are soluble in lighter fluid BUT insoluble in water.

18. 10/14/201518 Nucleic Acids -4 th Organic Compound -made up of carbon H, O, N and Phosphorus -There are only two type: -DNA -RNA

19. 10/14/201519 Function of nucleic acids: -To store and transmit our genetic code. Nucleic Acids are made up of many repeating units known as nucleotides. To Be Continued in a later chapter….
