Hemicelluloses dicotyledonous plants

Xyloglucans are the predominant hemicelluloses in the primary walls of edible vegetables and fruits of dicotyledonous plants. They are formed in the Golgi apparatus and secreted into the cell wall... [Pg.43]

Hemicelluloses have traditionally been defined by extraction procedures, i. e., hemicelluloses are those polysaccharides extracted by alkaline solutions from plant tissues after removal of low-molecular-weight substances with hot aqueous alcohol, removal of waxes and other lipid-soluble substances, delignification, and removal of pectin with an aqueous solution of a calcium ion chelator. The most abundant hemicelluloses in the primary cell walls of dicotyledons are xyloglucans. Xyloglucans have a backbone chain whose chemical stmcture is identical to that of cellulose. About 75% of the 8-D-glucopyranosyl units in that chain are substituted... [Pg.1424]
