Amylose differs from amylopectin in that amylose is
- A. highly branched through 1,6 glycosidic bonds
- B. a structural polymer of beta glucose
- C. largely unbranched and coils into a helix
- D. resistant to digestion by human amylase
Explanation
Amylose is an unbranched chain of alpha glucose that coils into a compact helix, while amylopectin carries frequent branches that give starch its many free ends for rapid enzyme attack. Cellulose, not amylose, is the beta glucose structural polymer that we cannot digest.
