What type of glycosidic linkages are present in amylose?

Options

  1. A-1,4
  2. B-1,6
  3. C-1,4 and -1,6
  4. D-1,4 and -1,6

Correct answer

A. -1,4

Step-by-step solution

Amylose consists of D-glucose units connected by - 1,4 glycosidic bonds, where the anomeric carbon (C-1) of one glucose is linked to C-4 of the adjacent unit in the configuration. While amylopectin features both - 1,4 and - 1,6 glycosidic linkages, and cellulose contains - 1,4 glycosidic linkages, amylose is uniquely characterized by - 1,4 glycosidic bonds. Final Answer: A. - 1,4 glycosidic linkages
