Chemically, amylose is a long unbranched chain with 200–1000 α-D-(+)-glucose units held together by C1C4 glycosidic linkage. Structure of glycogen is similar to amylopectin as it is a branched chain polymer of α-D-glucose units in which chain is formed by C1C4 glycosidic linkage whereas branching occurs by C1C6 glycosidic linkage.
