Description

Application

D-(−)-Arabinose is a D-ribose analogue present in sugar polymers such as the arabinogalatans of mycobacterial cell walls and plant tissues. D-Arabinose is a substrate used to identify, differentiate and characterize arabinose isomerase(s) that have commercial value in the production of tagatose, a low calorie sweetener.

Biochem/physiol Actions

D-Arabinose is a reducing sugar. It is a pentose analog of D-ribose that is a constituent of mycobacterial cell wall arabinogalactans. It is also a substrate for D-erythroascorbic acid synthesis in yeast.
