1. LIPID (FAT) NOTES

2. Lipids Waxy or oily compounds that store energy in their bonds Elements in lipids – carbon, hydrogen & oxygen Examples – fats, oils & waxes

3. Functions in the body **Long-term energy storage** Insulation Forms the protective membrane that surrounds each cell Some used as chemical messengers

4. Types of Lipids Saturated – fats that hold all the hydrogen that molecule can hold Examples: shortening & butter H H H H – C – C – C – O – H H H H

5. Types of Lipids, cont. Unsaturated – fats that have some spaces left in the molecule for hydrogen Examples: oils H C = C = C – O – H H

6. Building Blocks Fatty acids – the building blocks of fats (lipids)

7. Foods/Words that Indicate Lipids: Fats Oils Waxes Cottonseed oil, Palm oil, Soybean oil, Vegetable oil, Corn oil, Canola oil, etc. Vegetable Shortening Cholesterol Butter Animal Fat (Lard) Dairy Products (Milk, Cheese, Buttermilk, Cream etc.) Nuts (Peanuts, Almonds, etc.) Meat (Chicken, Pork, Beef, Bacon, etc.) Eggs (whole or yolks – not whites)

8. Food Energy 1 gram of lipids (fat) is 9 calories

10. NUCLEIC ACID NOTES

11. Nucleic Acids Molecules containing hydrogen, oxygen, nitrogen, carbon & phosphorus

12. Function in the body Store & transmit hereditary or genetic information

13. Building Blocks Nucleotides – the building blocks of nucleic acids Nucleotides have 3 parts: 5-carbon sugar A phosphate group A nitrogenous (nitrogen-containing) base

14. Examples Ribonucleic Acid (RNA) Deoxyribonucleic Acid (DNA)
