Starch is a polymer of a – glucose and consists of two components amylose and amylopectin. Amylose is a long unbranched chain with 200 – 1000 a D(+) glucose units held by C1 – C4 glycosidic linkage.
Amylopectin is a branched chain polymer of a D glucose units in which chain is formed by C1 – C4 glycosidic linkage branching occurs by C1 – C6 glycosidic linkage.
