What is the difference between amylose and amylopectin?

What is the difference between amylose and amylopectin?

Options

  1. AAmylopectin have 1→4α−1 \to 4\alpha - linkage and 1→6β−1 \to 6\beta - linkage.
  2. BAmylose have 1→4α−1 \to 4\alpha - linkage and 1→6β−1 \to 6\beta - linkage.
  3. CAmylopectin have 1→4α−1 \to 4\alpha - linkage and 1→6α−1 \to 6\alpha - linkage.
  4. DAmylose is made up of glucose and galactose.

Correct answer

C. Amylopectin have 1→4α−1 \to 4\alpha - linkage and 1→6α−1 \to 6\alpha - linkage.

Step-by-step solution

Amylose is long unbranched chain with α−D−\alpha - D - Glucosee with held by C1−C4{C}_{1} - {C}_{4} glucosidic linkage whereas amylopectin is branched chain polymer of α−D\alpha - D glucose unit in which chain is formed by C1−C4{C}_{1} - {C}_{4} glycosidic linkage while branching occurs by C1−C6{C}_{1} - {C}_{6} glucosidic linkage.
