  • 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 2
  • Concept map polymerisation Condensation polymerisation Naturally occurring Addition polymerisation synthethic
  • Slide 3
  • Condensation Polymerisation Naturally occurring CarbohydratesGlucoseProteinAmino acidsNucleotideNucleic acids
  • 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
