  • The stability of ascorbic acid in bottled cranberry-based beverages under home-use conditions

    Creator:
    Wong, Geoffrey K.
    Abstract:
    Commercially bottled, vitamin C-fortified, cranberry juice cocktail and cranberry-apple (cranapple) juice drinks were stored at 5°C under simulated home-use conditions. Ascorbic acid (AA) and dehydroascorbic acid (DHA) levels were evaluated over a period of seven days by high performance liquid chromatography (HPLC). Total vitamin C content was also determined by...

  • Immobilized cellooligosaccharides in the study of trichoderma reesei cellobiohydrolases

    Creator:
    Sangseethong, Kunruedee
    Abstract:
    A novel type of model substrates, i.e. immobilized p-aminophenyl-β-D-cellooligosaccharides, was developed and used in the study of exocellulases. The two major cellobiohydrolases from Trichoderma reesei, CBH I and CBH II were used as representative enzymes. p-Aminophenyl derivatives of cellobiose (PAPG₂), cellotriose (PAPG₃), and cellotetraose (PAPG₄) were synthesized from the reaction...

  • Studies towards the total synthesis of (-)-kendomycin

    Creator:
    Smits, Helmars
    Abstract:
    Studies towards the total synthesis of (−)-kendomycin (1), a bacterial metabolite with a unique molecular architecture and pronounced biological activity, are described. These studies resulted in the synthesis of advanced intermediate 208, containing all of the carbon atoms of 1. A Dötz annulation between alkyne 122 and novel chromium carbenoid...
