Identify the true statements regarding α-1, 6 linkages in glycogen. A. The number of sites for enzymes action on a glycogen molecule is increased through α-1, 6 linkages B. New α-1, 6 linkages can only form if the brancha has a free reducing endC. The reaction that forms α-1, 6 linkages is catalyzed by branching enzymesD. These linkages can only be formed on a chanin that is exactly 11 residues longE. Branching increase glycogen solubility.

C. The reaction that forms α-1, 6 linkages is catalyzed by branching enzymes.

Explanation:

α-glucan branching enzyme which can also be called the Brancher enzyme or glycogen-branching enzyme is the enzyme responsible for the side chain reaction that attaches at carbon atom 6 of a glucose unit (an α-1,6-glycosidic bond).

This branching enzyme attaches a string of seven glucose units to the carbon at the C-6 position on the glucose unit, forming the α-1,6-glycosidic bond.
