Xyloglucan is the main hemicellulose in the primary cell wall of dicotyledonous plants, and occurs in the cell walls of all vascular plants.Xyloglucan links cellulose microfibrils together, as well as avoid their adhesion and allow controlled creep. Chemistry Xyloglucan has a cellulosic semirigid backbone of β1→4-linked glucose residues that are substituted with a variety of 1-6 flexibly linked glycosidic sidechains. The most common sidechain is a single xylose residue, but longer… (More on Xyloglucan)
