1. HAPPY THURSDAY Bellwork: Copy this model onto your bellwork. Use this same information and your notes (from yesterday) to fill in the chart on Page 17 of your I.B.B. – only the carbohydrate column. Notecard definitions due TOMORROW.

2. Make sure your I.B.B.s are updated and organized.

6. Standard B.9A – Compare the structure and functions of different types of biomolecules. Essential Question How are lipids essential for life?

7. Lipids are molecules that are not soluble in water. They are nonpolar and hydrophobic.

8. The three categories of lipids include: Fats Oils Waxes

9. Lipids can be used to: Store energy. Contain the most energy per gram of any biomolecule. (9 Cal/gram) To form biological membranes and waterproof coverings. (waxy cuticle)

10. Many lipids are formed when a glycerol molecule combines with compounds called fatty acids.

11. Lipids contain only carbon (C), hydrogen (H), and oxygen (O).

12. Lipids Structure: Functions: Monomer:Polymer: Chain shaped A backbone and 3 tails Elements: C, H, O Source for long term energy Primary component of the cell membrane waxy coating on the top of leaves (cuticle). Good to know: Saturated fats: contain single bonds Unsaturated fats: contain double bonds Fatty acids Triglyceride (lipid) Fill in Chart

13. Biomolecule Foldable – Part 2 (Lipids) 1.Window Pane 2 a.Outline border with another color b.“Lipids” c.Draw a triglyceride molecule “E” d.Label the 3 “Fatty Acids” and “Glycerol Backbone” 2.Inside Window Pane 2 a.2 Functions b.2 Examples

16. Energy in Food Burning carbohydrates – watch and write down your observations Burning carbohydrates Burning lipids – take notes and write down any observations Burning lipids Calories in food – take notes…MAKE SURE you write down how many calories per gram in each biomolecule AND the daily recommended allowance Calories in food

17. As always, summarize what you have learned about carbohydrates and lipids in 36 words. In your summary, you must use the words: carbohydrates lipids energy
