Answer
- Equal to the number of branches plus one.
Explanation:
Glycogen is the multi branched polysaccharide of glucose units popularly known as animal starch, as it is chemically similar to starch. It has 30,000 glucose residues and a molecular weight of about 4.8 million. Glucose residues in glycogen are arranged in a highly branched bush like chains. There are two main linkage patterns, observed in glycogen, i.e., a 1-4 linkage in the straight part and a 1-6 linkage in the area of branching. The distance between two branching points is 10-14 glucose residues. Glycogen has as many non-reducing endsas branches plus one.
