1. Bellwork: Essays were due yesterday
Turn in rubric with name and period on it.
Copy and answer the following questions
When we added water, what process was occurring; dehydration synthesis or hydrolysis? Describe the glue after water was added.
When we added borax, what process was occurring; dehydration synthesis or hydrolysis? Describe the glue after borax was added.

2. The glue contains a polymer called polyvinyl acetate resin
The glue contains a polymer called polyvinyl acetate resin. We changed the polymer’s behaviors twice in this activity; once when we added water and the second time when we added borax.

6. Carbohydrates & Lipids

7. Objective: The objective of class today is to learn the structure and function of carbohydrates and lipids in living systems.

8. Living things use carbohydrates as their main source of energy
Living things use carbohydrates as their main source of energy. Plants and some animals also use carbohydrates for structural purposes.

9. The breakdown of sugars supplies immediate energy for all cell activities.

10. Living things store extra sugar as complex carbohydrates known as starches.

11. Single sugar molecules are called monosaccharides. (simple sugars)

12. Three examples of monosaccharides include:
Glucose
Galactose
Fructose

13. Large molecules made from monosaccharides are called polysaccharides.

14. Three examples of a polysaccharide include:

15. Carbohydrates Rings that link together in chains
Ratio of carbon: hydrogen: oxygen is 1:2:1
contain C, H, O
energy = 4cal/gram

16. Structure: Functions: Elements: Good to know: Carbohydrate Monomer:
Main source of immediate energy
Circle or ring shaped
Create a 1:2:1 ratio
Elements:
Good to know:
Often known as simple (monomers) and complex (polymers)
C, H, O
Carbohydrate
Monomer:
Polymer:
Polysaccharide
Examples: starch, cellulose
Monosaccharide
Examples: glucose, sucrose

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

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

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

23. 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.

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

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

26. As always, summarize what you have learned about carbohydrates and lipids in 30 words. In your summary, you must use the words: carbohydrates lipids energy
