  1. Lipids
    • hydrophobic
    • fats, waxes,steroids, oils
    • long term energy storage
    • insulate the body¬†
    • cushion and protect organs
  2. Saturated Fats
    • Single bonds(btwn C)
    • Straight chains
    • Solid @ room temp.
    • all animal fats= solid @ room temp.
  3. Unsaturated Fats
    • double bonds (@ least 1)
    • bent chains
    • liquid @ room temp. (oils)
    • found in plants
  4. Triglyceride
    • 4 monomers
    • glycerol + 3 fatty acids= 1 triglyceride
    • formed by condensation reaction between glycerol and fatty acid
    • 3 Ester bonds formed
  5. Fatty Acids
    Saturated or Unsaturated Fats
  6. Fats in Animals
    animals have high proportion of sat. fatty acids
  7. Lipids in Our Bodies
    • Cell Membrane- made up of phospholipids(lipids):¬†
    • head- polar; hydrophilic
    • 2 tails- nonpolar; hydrophobic
  8. Phospholipids
    glycerol+ 2 fatty acids+phosphate
  9. Bonds Formed
    Phosphodiester bonds
