Vedclass · Answer

(A) Starch is a polysaccharide,which is a polymer of $\alpha$-glucose units.It is formed by the condensation of glucose units linked by glycosidic bonds.The general formula of starch is $(C_6H_{10}O_5)_n$.It exists in two forms: amylose and amylopectin.Amylose is a linear polymer of $\alpha$-$D$-glucose units linked by $\alpha-1,4$-glycosidic bonds.Amylopectin is a branched polymer of $\alpha$-$D$-glucose units,where the main chain is linked by $\alpha-1,4$-glycosidic bonds and branching occurs via $\alpha-1,6$-glycosidic bonds.

List-$I$ $(\text{Saccharides})$	List-$II$ $(\text{Glycosidic linkages found})$
$(A)$ Sucrose	$(I)$ $\alpha 1-4$
$(B)$ Maltose	$(II)$ $\alpha 1-4$ and $\alpha 1-6$
$(C)$ Lactose	$(III)$ $\alpha 1-\beta 2$
$(D)$ Amylopectin	$(IV)$ $\beta 1-4$
