Noun
hemicellulose (plural hemicelluloses)
(biochemistry) A mixture of several plant polysaccharides, of smaller molecular weight than cellulose, that are soluble in dilute alkali; they are involved in the manufacture of paper, and are used in the production of furfural and ethanol.
Cellulose and hemicellulose are the basic structural material of the wood cells ; lignin acts as a kind of cell-bonding glue. Source: Internet
These three components are interwoven, and direct covalent linkages exist between the lignin and the hemicellulose. Source: Internet
Laccaria bicolor is lacking enzymes involved in the degradation of plant cell wall components (cellulose, hemicellulose, pectins and pectates), preventing the symbiont from degrading host cells during the root colonisation. Source: Internet
Not only regular sugars can be found in hemicellulose, but also their acidified form, for instance glucuronic acid and galacturonic acid can be present. Source: Internet
This is believed to be due to the decrease in the content of hemicellulose, crystallization of cellulose and changes to lignin over time resulting in the wood gaining better resonating properties. Source: Internet
