Hemicellulose interacts with the cellulose by providing cross-linking of cellulose microfibrils: hemicellulose will search for voids in the cell wall during its formation and provide support around cellulose fibrils in order to equip the cell wall with the maximum possible strength it can provide.

Plant mannans have β(1-4) linkages, occasionally with α(1-6) galactose branches, forming galactomannans.They are insoluble and a form of storage polysaccharide. Ivory nut is a source of mannans.
Cellulosic sugars are derived from non-food biomass (e.g. wood, agricultural residues, municipal solid waste). [1] The biomass is primarily composed of carbohydrate polymers cellulose, hemicellulose, and an aromatic polymer (lignin). The hemicellulose is a polymer of mainly five-carbon sugars C 5 H 10 O 5 .
It is a hemicellulose component in the cell walls of some plant species. Glucomannan is a food additive used as an emulsifier and thickener . It is a major source of mannan oligosaccharide (MOS) found in nature, the other being galactomannan , which is insoluble.

Xylose is the main building block for the hemicellulose xylan, which comprises about 30% of some plants (birch for example), far less in others (spruce and pine have about 9% xylan). Xylose is otherwise pervasive, being found in the embryos of most edible plants.
Xylan (/ ˈ z aɪ l æ n /; [3] / ˈ z aɪ l ən / [4]) (CAS number: 9014-63-5) is a type of hemicellulose, a polysaccharide consisting mainly of xylose residues. It is found in plants, in the secondary cell walls of dicots and all cell walls of grasses. [5]
Neutral detergent fiber (NDF) is the most common measure of fiber used for animal feed analysis, but it does not represent a unique class of chemical compounds.NDF measures most of the structural components in plant cells (i.e. lignin, hemicellulose and cellulose), but not pectin.
