  • Lipids
    • Low melting points
    • Do not form polymers
    • Used for storage, insulation and protection
    • Test for presence: Emulsion test
    • Fats and Oils
    • Made of: Glycerol and fatty acids
      • Glycerol: 3 carbons + 3 hydroxyl groups
      • Fatty acids are polar. COOH = hydrophillic
    • Triglyceride
      • 1 gylcerol + 3 fatty acids
      • Joins by condensation:  releases water molecule
      • Bonded by ester bonds
    • 1 fatty acid = monoglyceride 2 fatty acids = diglyceride
    • Phospholipids
      • 2 fatty acids + 1 phosphate group + 1 glycerol
        • Phosphate = hydrophillic
        • Fatty acid = hydrophobic
