Question

Identify the true statements regarding α‑1,6 linkages in glycogen.

(A) Branching increases glycogen solubility.
(B) New α‑1,6 linkages can only form if the branch has a free reducing end.
(C) The number of sites for enzyme action on a glycogen molecule is increased through α‑1,6 linkages.
(D) Exactly seven residues extend from these linkages.
(E) The reaction that forms α‑1,6 linkages is catalyzed by a branching enzym
