The diagram shows part of a molecule of glycogen. [Figure 10.1] How does the molecule differ from a molecule of amylose?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
AAmylose has only α-1,4 glycosidic bonds.
BAmylose has only β-1,4 glycosidic bonds.
CAmylose has α-1,6 glycosidic bonds with 1,4 linkages forming branches.
DAmylose has β-1,4 glycosidic bonds with 1,6 linkages forming branches.
✓ Correct answer
A: Amylose has only α-1,4 glycosidic bonds.
