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.
Xylan (/ˈzaɪlæn/;[3]/ˈzaɪlən/[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] Xylan is the third most abundant biopolymer on Earth, after cellulose and chitin.[citation needed]
