What is hemicellulose?

Hemicellulose is a collective term for non-digestible polysaccharides found in plant cell walls; it is composed of various monosaccharides, like xylose, mannose, galactose, rhamnose and arabinose. Hemicellulose is a dietary fiber, which can be either soluble or insoluble and more or less fermentable [1].

Xylans are hemicelluloses composed of only xylose, mannans of mannose, galactans of galactose, rhamnans of rhamnose and arabinans of arabinose. Various combinations, like galactomannans, glucomannans, arabonoxylans and arabinogalactans, exist.
