  1. 2-3 in-class notes-lipidsSTANDARD 1h MACROMOLECULE Human body fat cell

  2. MACROMOLECULE IS 1-CARBOHYDRATES • POLYMER IS • POLYSACCHARIDE---PLANT STARCH • MONOMER IS A • MONOSACCHARIDE • CALLED GLUCOSE WHICH IS A SIMPLE SUGAR

  3. 2-LIPIDS ARE THEMACROMOLECULE-POLYMER • MONOMERS • GLYCEROL + • FATTY ACIDS

  4. Lipids-fats-macromolecule ` • I. Organic compounds that are waxy or oily –not soluble in water • A. Roles of lipids

  5. 1. Store energy • 2. Form biological membranes • 3. Chemical messengers • B. Common Names • 1. Fats & waxes: Solid at room temp.

  6. 2. Oils: liquid at room temp • C. Made from 1. Mostly C &H atoms 2. specifically

  7. a. fatty acids-long chains of H & C atoms w/ a carboxyl group • 1. Carboxyl group 1C, 1H, 2 O atoms

  8. Glycerol-organic alcohol 1. 3 C atoms each Attached to a hydroxyl group(-OH) • Most lipids are formed with 2-3 fatty acids attached to glycerol

  9. D. Types of lipids 1. Saturated-C to C single bond a. Contains maximum # of H atoms

  10. b. meat & dairy • 2. Unsaturated C to C double bond a. Does not contain max. # of H atoms

  11. 3. Polyunsaturated-fatty acid contains many double bonds • Liquid at room temp 1. Cooking oils

  12. TRIGLYCERIDE IS A LIPID

  13. E. Other types • 1. Cholesterol a. Important part of cells; b. animal products c. Too much heart disease

  14. 2. Phospholipids- • Parts that dissolve in water & some that don’t • a. form cell membranes

  15. TRUE OR FALSE • FATS AND LIPIDS ARE THE SAME

  16. 2. FATS AND LIPIDS ARE • A. THE MACROMOLECULE • B. THE MONOMER • C. THE POLYMER • D. ORGANIC COMPOUND • E. ALL OF THESE LIST ALL THAT APPLY

  17. 3. WHAT IS THE MONOMER(S) FOR LIPIDS? • Glycerol and fatty acids
