Arabinose is a naturally occurring simple sugar ( monosaccharide ), which consists of five carbon atoms ( pentose ). It exists in the two enantiomers D-(- ) -arabinose and L- ( )- arabinose. Arabinose is sometimes also referred to as Pectinose, gum or sugar Aloinzucker. Arabinose can not be fermented by ordinary yeast. In 2005, researchers at the Goethe University Frankfurt am Main succeeded in modifying yeast cultures so that they can ferment and arabinose and xylose to ethanol.

The L- form is more common in food before, mostly as a building block in polysaccharide chains in the plant kingdom. The D-form has been shown as a component of a polysaccharide in tubercule bacilli.
