WebStarch or amylum is a polymeric carbohydrate consisting of numerous glucose units joined by α-(1→4)-D glycosidic bonds. This polysaccharide is produced by most green plants for energy storage. WebFigure 14.7. 1: Amylose. (a) Amylose is a linear chain of α-D-glucose units joined together by α-1,4-glycosidic bonds. (b) Because of hydrogen bonding, amylose acquires a spiral structure that contains six glucose units per turn. Amylopectin is a branched-chain polysaccharide composed of glucose units linked primarily by α-1,4-glycosidic ...
