Solved: CHEMISTRY Question for NEET

NEET CHEMISTRYMedium

The difference between amylose and amylopectin is:

Amylopectin has $1\rightarrow 4$ $\alpha$ -linkage and $1\rightarrow 6$ $\alpha$ -linkage.

Amylose has $1\rightarrow 4$ $\alpha$ -linkage and $1\rightarrow 6$ $\beta$ -linkage.

Amylopectin has $1\rightarrow 4$ $\alpha$ -linkage and $1\rightarrow 6$ $\beta$ -linkage.

Amylose is made up of glucose and galactose.

Step-by-Step Solution

Starch consists of two components: amylose and amylopectin. Amylose is a linear polymer of $\alpha$ -D-glucose units connected by C1-C4 glycosidic linkages ( $1\rightarrow 4$ $\alpha$ -linkage). Amylopectin is a highly branched polymer of $\alpha$ -D-glucose. In amylopectin, the linear chain is formed by C1-C4 glycosidic linkages ( $1\rightarrow 4$ $\alpha$ -linkage), whereas branching occurs by C1-C6 glycosidic linkages ( $1\rightarrow 6$ $\alpha$ -linkage).
