Describe the synthesis of triglyceride by the formation of ester bonds during condensation reactions between glycerol and three fatty acids and recognise differences between saturated and unsaturated lipids. (Activity 1.16)

HideShow resource information
  • Three fatty acids and one glycerol molecule make up one triglyceride molecule.
  • The molecules bond with an ester bond again a condensation reaction.
  • The bond is between an oxygen and carbon atom (the carbon has a double bond between an oxygen).
  • A saturated lipid has a chain of hydrocarbons which is saturated with hydrogen atoms.
  • An unsaturated lipid
