Xylose

A pentose sugar, referred to in the early literature as l -xylose. It is present in many woody materials. The polysaccharide xylan, which is closely associated with cellulose, consists practically entirely of d- xylose. Corncobs, cottonseed hulls, pecan shells, and straw contain considerable amounts of this sugar. This pentose sugar is also a component of the hemicelluloses and the rare disaccharide, primeverose.
