Glycogen is a massive, highly efficient energy storage polysaccharide heavily deposited in the liver — Biomolecules Chemistry Question
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?
💡 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.
