- Slide 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

- Slide 4
- Addition Polymerisation synthetic thermoplastic Alkenes Thermosetting plastics Alkenes
- Slide 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.
- Slide 6
- Slide 7
- Monomers & functional groups
- Slide 8
- Combinations of different units
- Slide 9
- Glucose molecule
- Slide 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.
- Slide 11
- Combination of glucose units
- Slide 12
- Repeating unit
- Slide 13
- Amino acid units
- Slide 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.
- Slide 15
- Monomer/Polymer/Cellular structure
- Slide 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)
- Slide 17
- Polymerisation

- I am only one, but still I am one. I cannot do everything, but still I can do something. I will not refuse to do the something I can do. Helen Keller
