描述

應用

D-Xylose, an aldopentose, is used as a feed stock to produce the non-caloric sweetener, xylitol and commercially valuable ethanol. D-Xylose may be used in intestinal function research to test for small intestinal malabsorption.

生化／生理作用

D-Xylose, a principle hemicellulosic sugar in plants and hardwoods, is a main building block for xylan.
