From Wikipedia, the free encyclopedia
Xyloglucan is the main hemicellulose in the primary cell wall of dicotyledonous plants. Xyloglucan links cellulose microfibrils together.

[edit] Chemistry
Xyloglucan has a backbone of ß1→4-linked glucose residues that are substituted with a variety of glycosidic sidechains. The most common sidechain is a single xylose residue, but longer sidechains that include the sugars galactose and fructose are also common.
[edit] Biosynthesis
Xyloglucan is synthesised in the Golgi and is transported to the cell membrane by vesicles <ref>Moore PJ and Staehelin LA (1988).
