        • Glycerol
        • Fatty acids
          • 1 molecule of glycerol joined to 3 molecules of fatty acids
            • Glycerol
    • Proteins
      • Made up from 20 different sub-units
        • Amino Acids
          • Linked together in long chains which are usually folded up or twisted into spirals
            • Order of amino acids decides its shape.
              • Lots of different orders-
