   hemicellulose
   Class of plant cell-wall polysaccharide that cannot be extracted from the wall by hot water or chelating agents, but can be extracted by aqueous alkali. Includes xylan, glucuronoxylan, arabinoxylan, arabinogalactan II, glucomannan, xyloglucan, and galactomannan. Part of the cell-wall matrix.

   Hemicellulose
   A `hemicellulose` can be any of several heteropolymers (matrix polysaccharides) present in almost all cell walls along with cellulose. While cellulose is crystalline, strong, and resistant to hydrolysis, hemicellulose has a random, amorphous structure with little strength. It is easily hydrolyzed by dilute acid or base as well as myriad hemicellulase enzymes.

   hemicellulose
   (hem″e-sel´u-lōs) a food fiber composed of various sugars, including xylose, glucose, and mannose. Hemicelluloses absorb and retain water in the gut but have little effect on stool size, and are largely digested by gastrointestinal bacteria.
