    HPLC-gold standard method

  • 21

    Types of Oxidation Reduction

    Folin Wu, Nelson Somogyi, Neocuproine, Benedict’s Method

  • 22

    Type or Condensation

    Orthotoluidine

  • 23

    Principle: Cupric ions reduced to cuprous ions forming cuprous oxide in hot alkaline solution by glucose

    Cupric Ion Reduction

    Interfering substance used in ortho-toluidine

    Galactose and Mannose

  • 29

    Types of glucose oxidase

    Polarographic Method

  • 35

    H2O2 is removed by two additional reactions called:
