The difference between amylose and amylopectin is
  • ✓
    Amylopectin have $1 \rightarrow 4 \alpha$ -linkage and $1 \rightarrow 6\alpha$ -linkage 
  • B
    Amylose have $1 \rightarrow 4 \alpha$-linkage and $1 \rightarrow 6\beta$-linkage 
  • C
    Amylopectin have $1 \rightarrow 4 \alpha$ -linkage and $1 \rightarrow 6 \beta-$linkage 
  • D
    Amylose is made up of glucose and galactose
✓

Answer

Correct option: A.
Amylopectin have $1 \rightarrow 4 \alpha$ -linkage and $1 \rightarrow 6\alpha$ -linkage 
a
Amylose is long unbranched chaln with $\alpha-\mathrm{D}$ - Glucose with held by $\mathrm{C}_{1}-\mathrm{C}_{4}$ glucosidic linkage whereas amylopectin is branched chain polymer of $\alpha -D$ glucose unit in which chain is formed by $\mathrm{C}_{1}-\mathrm{C}_{4}$ glycosidic linkage while branching occurs by $\mathrm{C}_{1}-\mathrm{C}_{6}$ glucosidic linkage.
