What is the difference between amylose and amylopectin?

Options

  1. AAmylopectin have 1 → 4      α - linkage and 1 → 6    β - linkag
  2. BAmylose have 1 → 4    α - linkage and 1 → 6      β -   lin
  3. CAmylopectin have 1 → 4    α - linkage and 1 → 6    α - linkage.
  4. DAmylose is made up of glucose and galactose.

Correct answer

C. Amylopectin have 1 → 4    α - linkage and 1 → 6    α - linkage.

Step-by-step solution

Amylose is long unbranched chain with α - D - Glucosee with held by C 1 - C 4 glucosidic linkage whereas amylopectin is branched chain polymer of α - D glucose unit in which chain is formed by C 1 - C 4 glycosidic linkage while branching occurs by C 1 - C 6 glucosidic linkage.
