  • Polysaccharides
    • Starch
      • Structure
        • Insoluble, forms starch granules
        • Mixture of amylose and amylopectin
          • Amylose - chain of glucose, helix
          • Amylopectin - branches give an open structure, broken down quicker
          • Broken down by amylase into maltose
        • a glucose
          • Flexible
      • Function
        • Plant pollysaccharide storage
    • Cellulose
      • Function
        • Only found in plants, mainly cell walls
      • Structure
        • Isomer of glucose
        • B glucose
          • Rigid
          • Straight
          • Broken down by cellulose in bacteria
      • Beta glucose
        • different position of hydroxyl group
        • Alternate glucose molecules are inverted
        • Linked chains - cellulose microfibrils
          • Strength to plants
    • Glycogen
      • Structure
        • Highly branched, mobilised quickly
        • Linear chains of glucose
          • Broken down by glycogen phosphorylase
        • a glucose
          • Flexible
      • Function
        • Animal polysaccharide storage, mainly in muscle and liver.
        • Quick sauce of energy

i like it :) nice and simple- easy reference! one thing - 'Quick sauce' should be 'quick source' :)
