1. LIPIDS

2. ELEMENTS CARBON (C) HYDROGEN (H) OXYGEN (O)

3. BUILDING BLOCKS (MONOMERS) FATTY ACIDS (3) GLYCEROL

4. FUNCTIONS 2 ND SOURCE OF ENERGY MAKES UP THE CELL MEMBRANE InSULATION

5. GROUPS WAXES FATS OILS BEESWAX OLIVE OIL BUTTER

6. TESTS Indicator=BROWN PAPER –T–TRANSLUCENT SPOT (LIGHT SHINES THROUGH), INDICATES THAT A LIPID IS PRESENT

7. EXAMPLES OF MOLECULES PHOSPHOLIPIDS - (MAKES UP MAJORITY OF THE CELL MEMBRANE) Steroids –Example: cholesterol

8. UNIQUE CHARACTERISTICS SATURATED (single bonds between all carbon atoms -SO completely surrounded(saturated) with hydrogen atoms  UNSATURATED (DOUBLE BONDS between carbon atoms SO LESS H around Carbon ) INSOLUBLE IN WATER

10. HOW IT GETS IN OUR BODY OILS WE COOK WITH –O–OLIVE OIL –C–COCONUT OIL –P–PEANUT OIL ANIMAL FAT –M–MEAT FAT –D–DAIRY PRODUCTS BUTTER CREAM/WHOLE MILK
