Lipids

  • describe the molecular structure of a triglyceride with reference to the formation of ester bonds and relate the structure of triglycerides to their functions in living organisms
  • describe the structure of a phospholipid and relate the structure of phospholipids to their functions in living organisms
  • recall that triglycerides are formed by the condensation of one molecule of glycerol and three molecules of fatty acid
  • recall that a condensation reaction between glycerol and a fatty acid (RCOOH) forms an ester bond
  • describe the different properties of triglycerides and phospholipids related to their different structures
  • describe the emulsion test for lipids
  • recognise, from diagrams, saturated and unsaturated fatty acids
