Answer 1

1. Lipids consist of carbon hydrogen and oxygen

2. Triglycerides

3. Triglycerides have one glycerol back bones and three fatty acid chains

4. There are three types of fatty acid - saturated: they have no double bonds. Monounsaturated - they have one double bond and polyunsaturated they have more than one double bonds

5. Because a carbon can make 4 bonds if two carbons are making double bond they each will have 2 hydrogen bonds instead of three

6. Milk based and meat products are high in saturated fat

7. Coconut oil

8. Olive oil
