14.8 What is the basic structural difference between starch and cellulose?
Cellulose is a long straight-chain polysaccharide made of - D - glucose units and has 1,4 - glycoside linkage.
Whereas starch is made up of 2 components:- Amylose and amylopectin.
Amylose is a long straight chain made of - D - glucose units and joined by 1,4 - glycosidic linkage.
Amylopectin is a branched structure and chains are formed at 1,4 - glycoside linkage and branching occurs at 1.6 - glycosidic linkage.
