LIPIDS SECTION 1-8 P.36-37

CHARACTERISTICS MADE UP OF C, H, O BUT H TO O RATIO IS NOT 2:1 THE MONOMER IS THE FATTY ACID (ALONG WITH GLYCEROL)

CHARACTERISTICS THEY ARE HYDROPHOBIC MOLECULES (MEANINGTHEY CANNOT DISSOLVE IN WATER ) USED FOR INSULATION, PROTECTION, AND STORAGE STORE MORE ENERGY PER GRAM THAN CARBOHYDRATES

TYPES OF LIPIDS 1.FATS  A.SATURATED (SOLID AT ROOM TEMP., IN ANIMALS, NO DOUBLE BONDS IN TAILS) B.UNSATURATED (LIQUID AT ROOM TEMP., IN PLANTS, DOUBLE BONDS IN TAILS) 2. OILS  COOKING

TYPES OF LIPIDS 3.WAXES  EAR, PLANT LEAVES (FOR PROTECTION) 4.PHOSPHOLIPIDS  IMPORTANT TO CELL STRUCTURE AND FUNCTION SINCE THEY MAKE UP CELL MEMBRANES

TYPES OF LIPIDS 5.STEROIDS  SEX HORMONES (ESTROGEN, TESTOSTERONE) AND CHOLESTEROL  IN CELL MEMBRANES, SYNTHESIZED AND REGULATED IN THE LIVER, BUILD UP IN ARTERIES CAN LEAD TO ATHEROSCLEROSIS
