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.

hem·i·cel·lu·lose

(hem'ē-sel'yū-lōs),
Plant cell-wall polysaccharides closely associated with cellulose, for example, xylans, mannans, and galactans.
Synonym(s): cellulosan

hemicellulose

(hĕm′ĭ-sĕl′yə-lōs′, -lōz′)
n.
Any of several branched polysaccharides that are composed of a variety of different monosaccharides and form a matrix with cellulose and lignin or pectin in plant cell walls. It is produced commercially from corn fiber.

hem·i·cel·lu·lose

(hem'ē-sel'yū-lōs)
An indigestible carbohydrate similar to cellulose, found in a plant's water-absorbing outer layer.

hemicellulose

a polysaccharide associated with cellulose and LIGNIN, found in plant cell walls.

It is evident from the above discussion that the physicochemical structure of hemicellulose and lignin changes rapidly on increasing the temperature.
Figure 3 clearly shows the increase in [RI.sub.1730] related to chromophore formation while lignin structures are destroyed (decrease in [RI.sub.1510]) and a--within the error margin--constant [RI.sub.1330] of cellulose and hemicellulose. Changes are very fast within the first 100 h of exposure, followed by flattening out in a plateau value.
Finding a way to process cellulose and hemicellulose together would make the process simpler and cheaper.
Dry wood is composed of fibers of cellulose and hemicellulose held together by lignin.
The composition of the hays differed (P [less than or equal to] 0.05) among endophyte status for IVTDMD, CP, NDF, hemicellulose, and cellulose, but not for ADF or lignin (Table 5).
The cell walls of plants can be compared to reinforced concrete in which the reinforcing steel bars are represented by the cellulose fibrils, and the concrete is represented by the matrix material that includes hemicellulose and an indigestible polymer called lignin.
Green bananas are rich in nondigestible fibers including cellulose, hemicellulose, and [alpha]-glucans that ferment in the colon and become short-chain fatty acids.

Bleach strips away the wood lignin and hemicellulose and leaves acid-free fibers (about 50% of the original wood content) for paper making and specialty applications.
Each serving of Healthy Essentials contains 25 vitamins and minerals in addition to hemicellulose, which is associated with digestive health and enhancing the immune system.
Pentosan -- referring to a hemicellulose found in cereal, straw and other woody plants -- is normally too big to enter the brain from blood vessels.
