  • Carbohydrates
    • Starch
      • Found in plants
      • Made of alpha glucose
      • Polysaccharide
      • Storage molecule
      • Tightly coiled to be more compact
      • linear and helical amylose
      • low solubility is because it is a polymer consisting of many glucose molecules joined by glycosidic bonds
      • amylose
        • unbranched
        • 1-4 glyosidic bonds
        • coiled
      • amylopectin
        • long branched chain
        • 1-4 and 1-6 glyosidic bonds
        • side branches allow enzyme to break easily
    • Glycogen
      • Found in animals
      • Made from alpha glucose
      • Polysaccaide
      • Branched chain to easily be broken down
      • Storage molecule
      • glyosidic bonds
      • structure similar to amylopectin (a component of starch) but is more extensively branched and compact than starch.
    • Cellulose
      • Found in plants
      • Made from Beta Glucose
      • Structural molecule
      • Cell Walls
      • Unbranched chain of alternating molecules
      • Hydrolysed to form alpha glucose for respiration
      • Glyosidic bonds
