(1→4)-β-D-xylan is a polymer of β-D-xylopyranose residues connected by (1→4) links. It is found in the cell walls of plants and some green and red algae, and is the major constituent of hemicellulose. Pure xylan, consisting of only xylopyranosyl residues, is rare. Most forms of a (1→4)-β-D-xylan are decorated with other types of sugar.
Reactions known to consume the compound:
UDP-α-D-xylose + [(1->4)-β-D-xylan](n) → UDP + [(1->4)-β-D-xylan](n+1)
UDP-β-L-arabinopyranose + a (1→4)-β-D-xylan → an arabinoxylan + UDP
UDP-α-D-glucuronate + a (1→4)-β-D-xylan → a glucuronoxylan + UDP
