Triglycerides

    Cards (8)

    • Triglycerides contain 3 fatty acids and 1 glycerol
    • Triglycerides undergo hydrolysis with 3 water molecules to produce 1 glycerol and 3 fatty acids
    • Structure of a triglyceride: high ratio of energy storing C-H bonds to carbon atoms. Low mass to energy ratio. Large, non polar molecule. high ratio of oxygen to hydrogen atoms
    • Properties of a triglyceride: a lot of energy is released when bonds are broken. A lot of energy can be stored in a small space. Insoluble in water. release water during condensation reactions.
    • Functions of triglycerides: an excellent store of energy. Good storage Molecule. Does not affect the water potential of the cell. Important source of water for the cell
    • Explain how triglyceride structure enables it to be an important source of water for the cell?
      • triglycerides are condensed and release 3 water molecules
      • this means a lot of water is released during condensation reactions
    • Saturated triglyceride: FATS
      •contain strong intermolecular forces
      • takes a lot of energy to break bonds
      high melting and boiling point
      SOLID at room temperature
    • Unsaturated triglyceride: OILS
      weak intermolecular forces
      • takes little energy to break bonds
      low melting and boiling point
      LIQUID at room temperature
