Plant cells are surrounded by a rigid wall made up of cellulose microfibrils, pectins, hemicelluloses, and lignin. This cell wall provides structure and protection for plant cells. In grasses and in dicot secondary cell walls, the major hemicellulose is a polymer of β-(1,4)-linked xylose units called xylan.

Outstanding questions on xylan biosynthesis
Plant Science, 2022Xylan is the second most abundant polysaccharide in plant biomass. It is a crucial component of cell wall structure as well as a significant factor contributing to biomass recalcitrance. Xylan consists of a linear chain of β-1,4-linked xylosyl residues that are often substituted with glycosyl side chains, such as glucuronosyl/methylglucuronosyl and ...

Xylan-degrading activity in yeasts: Growth on xylose, xylan and hemicelluloses
Folia Microbiologica, 1978The ability to grow in liquid media with D-xylose, xylan from decidous trees, and hemicelluloses from conifers was tested in 95 strains of 35 genera of yeasts and yeast-like organisms. Of 54 strains thriving on xylose, only 13 (genera Aureobasidium, Cryptococcus and Trichosporon) utilized xylan and hemicelluloses as growth substrates.

The Xylan of Rhodymenia palmata
Nature, 1950Barry and Dillon1 reported the isolation from the red seaweed Rhodymenia palmata of a polysaccharide which gave D-xylose on hydrolysis. Our special interest in xylans2 has led us to investigate this substance more fully as part of the research programme of the Scottish Seaweed Research Association.

Xylan was 2-hydroxypropylsulfonated and/or 2-hydroxypropylquaternized for film application. All the products were water soluble with molar masses of the derivatives between Mn of 3.8 and 948.9 kg/mol with polydispersity index D from 1.7 to 26.8. At the range from 100 to 250 ?m of thickness the material developed reproducible mechanical properties. When

A PREVIOUS investigation1 has shown that enzymes from Chœtomium globosum are able to hydrolyse wheat straw xylan to xylose with the formation of a series of intermediates, designated a,b,c, … g, which appear on paper-chromatograms with regularly decreasing RF-values, and which are believed to be oligosaccharides with regularly increasing xylose units ...

Conformational analysis of xylan chains
Carbohydrate Research, 2005The present study provides a theoretical description of the different levels of structural organization that characterize the xylan polysaccharide in its native and hydrophobic lauroyl esterified forms. The goal of this study was to ascertain the role played by the hydroxyl or lauroyl side groups on the conformational flexibility of the xylan chain ...

Xylan of Siphonaceous Green Algae
Nature, 1960COMPARATIVELY little is known at present about the chemical nature of the cell wall constituents of siphonous green algae, especially that of the non-septate groups. Although the cell wall of the algae belonging to Bryopsidaceae, Caulerpaceae and Codiaceae has been stated to consist for the most part of callose (a name given originally to a ...
