Name the polymer in which chains are formed by -1,4-glycosidic linkages between -glucose units and branches are formed by -1,6-glycosidic linkages.

Options

  1. AAmylose
  2. BAmylopectin
  3. CStarch
  4. DCellulose

Correct answer

B. Amylopectin

Step-by-step solution

Amylopectin is a branched-chain polymer of -D-glucose units. The linear chain is formed by -1,4-glycosidic linkages between the -D-glucose units. The branching occurs through -1,6-glycosidic linkages. Amylose is a linear polymer with only -1,4-glycosidic linkages. Cellulose is a linear polymer of -D-glucose units with -1,4-glycosidic linkages. Starch is a mixture of both amylose and amylopectin. Answer: Amylopectin
