Cellulose is a long straight-chain polysaccharide made of  \beta -  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 \alpha - 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.
