• monomers are the smaller units from which larger molecules are made
• polymers are molecules made from a large number of monomers joined together
• monomer ex

  • monosaccharide
  • amino acids
  • nucleotides
• a condensations reaction joins two molecules together with the formation of a chemical bond and involves the elimination of a molecule of water
• a hydrolysis reaction breaks a chemical bond between two molecules and involves the use of a water molecule
• a macromolecule is a large complex molecule
• polymerisation

  • the process of making a polymer from monomers
• polymerisation is a condensation reaction
• water is a product of a condensation reaction
• hydrolysis reaction has water as a reaction (left)
• condensation reaction has water as a products (right)
• a condensation reaction is

  • joining monomers together
  • bonds are formed
• polymers are large and complex molecules
• isomer

  • same molecular formula but a different structural formula
• condensation has a product of water
• hydrolysis is using water to break the reaction
