Question

Glycogen is a massive, highly efficient energy storage polysaccharide heavily deposited in the liver and muscles of animals. Structurally, glycogen is chemically identical in its linkage motifs to which specific prominent plant carbohydrate fraction?

Answer: C

💡 Solution & Explanation

Glycogen (frequently referred to as "animal starch") possesses a highly branched structural architecture identical to that of plant amylopectin. Both heavily utilize a main continuous $\alpha-1,4$ glycosidic chain interspersed periodically with $\alpha-1,6$ glycosidic branching points, though glycogen branches significantly more frequently.
