  • Structure of polymer relating to function
    • What is a polymer?
    • Storage Carbohydrates
      • Amylose
        • Insoluble so doesn't affect water potential
        • Helical so compact
        • Alpha glu monomers, storage of energy in plant cells
      • Glycogen
        • Insoluble, does not affect water potential
        • Many ends allow fast energy release for animal cells
        • Highly branched so compact
    • DNA
      • Bases
        • Carries genetic code in sequence of bases
        • Allows precise replication due to specific base pairing
    • RNA
      • Structure
      • Ribosomal RNA
    • Polypeptides
      • Fibrous Proteins
        • Collagen in connective tissue
        • Keratin in hair and finger nails
      • Globular proteins
        • Haemoglobin
        • Enzymes
        • Hormones
      • Structure
        • "Explain level of protein structure"
    • Structural Carbohydrates
      • Cellulose
        • beta glucose monomers, every other inverted
        • Structural; offers support and prevents bursting of cell wall
        • Insoluble, strong and resistant to hydrolysis
        • Many hydrogen bonds form microfibrils
      • Chitin
  • Structure
    • Very stable due to sugar phosphate backbone
    • Very long and helical so compact
    • DNA
      • Bases
        • Carries genetic code in sequence of bases
        • Allows precise replication due to specific base pairing
  • Role in protein synthesis
    • mRNA
    • tRNA
    • RNA
      • Structure
      • Ribosomal RNA
