What is the basic structural difference between starch and cellulose?
(N/A) Starch consists of two components: amylose and amylopectin.
Amylose is a long linear chain of $\alpha-D-(+)-$glucose units joined by $C1-C4$ glycosidic linkage ($\alpha-$link).
Amylopectin is a branched-chain polymer of $\alpha-D-$glucose units,in which the chain is formed by $C1-C4$ glycosidic linkage and the branching occurs by $C1-C6$ glycosidic linkage.
On the other hand,cellulose is a straight-chain polysaccharide of $\beta-D-$glucose units joined by $C1-C4$ glycosidic linkage ($\beta-$link).
Amylose is a long linear chain of $\alpha-D-(+)-$glucose units joined by $C1-C4$ glycosidic linkage ($\alpha-$link).
Amylopectin is a branched-chain polymer of $\alpha-D-$glucose units,in which the chain is formed by $C1-C4$ glycosidic linkage and the branching occurs by $C1-C6$ glycosidic linkage.
