Biochem Lab Activity 3: Qualitative Analysis of Carbohydrates

  1. reducing sugars may be differentiated from each other by the osazones they form with __________
    phenylhydrazine
  2. are yellow crystalline compounds
    osazone
  3. used to differentiate helical from non helical/linear polysaccharides
    iodine solution
  4. amylose trap iodine molecules, producing what color
    deep-blue black complex
  5. amylopectin which is branched and helical, gives _____________ color with iodine
    purple or red violet
  6. glycogen gives color varying from ______ to _______
    wine red to brown
  7. ___________, __________, ____________, and _________ have linear structure and thus give no color with iodine or the color of iodine is retained
    cellulose, inulin, gum-arabic, agar-agar
  8. Monosaccharide and disaccharide do not form dark colors with iodine because
    they are too small to trap iodine molecules
