The Linkage Between the Glucose Residues in Amylopectin and Glycogen

The linkage between the glucose residues in amylopectin and glycogen is:

A) For the main chain α (1 → 4) and β (1 → 4) for the branches
B) For the main chain α (1 → 6) and α (1 → 4) for the branches
C) For the main chain α (1 → 4) and α (1 → 6) for the branches
D) For the main chain β (1 → 4) and β (1 → 6) for the branches
E) The linkage between the glucose residues is variable.
