1. MACROMOLECULES EXAMPLE IS NOT THE MAIN THING IN INFLUENCING OTHERS. IT IS THE ONLY THING. ALBERT SCHWEITZER Ch.16 J.C. Rowe Windsor University School of Medicine

4. Addition Polymerisation synthetic thermoplastic Alkenes Thermosetting plastics Alkenes

5. Macromolecules  Large molecules  Macromolecules are formed when monomers are linked together to form longer chains called polymers.  The same process of making & breaking polymers is found in all living organisms.

7. Monomers & functional groups

8. Combinations of different units

9. Glucose molecule

10. Formation of starch  Starch is formed from 2 monomer units, glucose & fructose, which link together via condensation reaction to produce the disaccharide sucrose.  The enzyme salivary amylase, found in saliva, hydrolyses starch into its monomer units.

11. Combination of glucose units

12. Repeating unit

13. Amino acid units

14. Proteins  Proteins are made up of amino acid monomer units.  The amino end (-NH2) of one amino acid join up with the acid end (-COOH) of another amino acid to form a peptide bond.

15. Monomer/Polymer/Cellular structure

16. Plastics  Addition polymers are formed by subjecting the monomer to high pressure & temperature in the presence of a catalyst.  Polyesters & polyamides (nylon) are synthetic fibers made from condensation polymerisation.  There are 2 types of plastics : thermoplastics (easily remoulded) & thermosetting plastics (cannot be re- melted or remoulded)
