polysaccharides

Cards (12)

  • how do you form a polysaccharide
    condensation reaction between monosaccharides
  • how do you form a monosaccharide
    hydrolysis reaction
  • what is the function of starch
    glucose is stored as starch in a plant
  • what are the different examples of starch
    amylose, amylopectin
  • what is the structure and function of amylose
    long, unbranched chain
    angles of glycosidic bonds give amylose a coiled structure - makes it compact so good for storage
  • what is the structure and function of amylopectin
    long, branched chain of alpha glucose
    side branches allow enzyme to get at the glycosidic bonds easier so the glucose is released quickly
  • why is starch insoluble
    so it doesn't affect water potential and therefore it is good for storage
  • what is glycogen used for
    storing excess glucose as glycogen in animals
  • what is the structure of glycogen
    long, with lots more side branches
  • how does the structure of glycogen relate to its function
    side branches - glucose is released quicker
    compact - good for storage
  • what is the structure of cellulose
    long, unbranched chain of beta glucose linked by hydrogen bonds, forming strong microfibrils
  • how do microfibrils benefit cellulose
    provides structural support for cells
