Polymers are large molecules built up from small molecules. State the name given to the small molecules from which polymers are made. The formula of a polymer is shown. n C CH3 C CH3 H H Draw the structure of the small molecule from which this polymer is made. Show all of the atoms and all of the bonds.  State the type of polymerisation used to make this polymer. Three amino acids are shown. They combine to form part of a natural polymer. H2N COOH H2N COOH H2N COOH Name the type of natural polymer formed when amino acids combine. Complete the diagram to show part of the structure of the natural polymer that forms when these three amino acids combine. Show all of the bonds in the linkages.  Name the type of chemical reaction that takes place when this natural polymer is converted back to amino acids.
