    A hemicellulose (also known as ... 500–3,000 sugar units. ... Homoxylans mainly have structural functions. Heteroxylans such as glucuronoxylans ...

  3. Xylan - Wikipedia

    en.wikipedia.org/wiki/Xylan

    Structure of xylan in hardwood. [1] Plant cell wall is composed of cellulose, hemicellulose, pectin and glycoproteins. [2] Hemicelluloses (a heterogeneous group of polysaccharides) cross-link glycans interlocking the cellulose fibers and form a mesh like structure to deposit other polysaccharides.

  4. Mannans - Wikipedia

    en.wikipedia.org/wiki/Mannans

    Mannans are polymers containing the sugar mannose as a principal component. [1] [2] They are a type of polysaccharide found in hemicellulose, a major source of biomass found in higher plants such as softwoods. These polymers also typically contain two other sugars, galactose and glucose

  5. Xylose - Wikipedia

    en.wikipedia.org/wiki/Xylose

    Xylose (cf. Ancient Greek: ξύλον, xylon, "wood") is a sugar first isolated from wood, and named for it. Xylose is classified as a monosaccharide of the aldopentose type, which means that it contains five carbon atoms and includes an aldehyde functional group. It is derived from hemicellulose, one of the main constituents of biomass. Like ...

  6. Cellulosic sugars - Wikipedia

    en.wikipedia.org/wiki/Cellulosic_sugars

    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 . [2] and the cellulose is a polymer of six-carbon sugar C 6 H 12 O 6 . [3]

  7. Lignocellulosic biomass - Wikipedia

    en.wikipedia.org/wiki/Lignocellulosic_biomass

    A particular problem is that hemicellulose is covalently linked to lignin, usually through ferulic acid component of the lignin. This makes it difficult to extract the sugars necessary for conversion to biofuels. [11] Next to cellulose hemicellulose is the second most abundant source of carbohydrates in a plant. [12] cellulose is a homopolymer ...

    en.wikipedia.org/wiki/Xylanase

    Endo-1,4-β-xylanase (EC 3.2.1.8, systematic name 4-β-D-xylan xylanohydrolase) is any of a class of enzymes that degrade the linear polysaccharide xylan into xylose, [1] thus breaking down hemicellulose, one of the major components of plant cell walls: Endohydrolysis of (1→4)-β-D-xylosidic linkages in xylans
