D(-)-Arabinose Usage And Synthesis

Chemical Properties

White to off-white powder

Uses

An inhibitor of the enzyme glucose dehydrogenase.

Purification Methods

Crystallise D-(-)-arabinose three times from EtOH, dry it in vacuo at 60o for 24hours and store it in a vacuum desiccator. It also crystallises from a mixture of H2O/MeOH/EtOH with m 158-160o, or H2O with m 160-161o. [Whistler & Schweiger J Am Chem Soc 81 5190 1959, Fletcher et al.
