Glycogen is a branched polymer of glucose in which the straight chains are linked by glycosidic bonds and the branch points are formed by glycosidic bonds. It has a single reducing end and several non-reducing ends, and degradation or synthesis occurs mainly at the non-reducing ends. In the given diagram, and represent non-reducing ends while is the only reducing end. The branching points C and D contain , 6 linkages, not bonds. Therefore, out of the given statements, only statement is correct. Hence, the correct answer is only one.
