So the glycogen branching enzyme detaches a group of seven or more glucose residues that contain a terminal residue and attach that group via an Alpha One Six glycocitic bond, somewhere on the interior of that particular glycogen molecule. Now, the branching enzyme actually requires two things. Firstly, it requires that the original glycogen chain on which we begin working on is at least eleven residues in length. And it also requires that it is placed at least four residues away from any preexisting branching point. And to see what all that means, let's take a look at the following hypothetical example. So let's suppose this is our initial glycogen molecule that we begin with.
