Question

The number of ends in a glycogen molecule would be

• A. Equal to the number of branches plus one
• B. Equal to the number of branch points
• C. One
• D. Two, one on the left side and another on the right side

Answer 1

Answer: (A)

Equal to the number of branches plus one

Glycogen is a polysaccharide made up of glucose units. It s a major storage sugar in animals. It is a branched polysaccharide wherein, glucose molecules form a chain and are linked by alpha-1-4 linkage and the branch of glucose is linked to the chain by alpha-1-6 linkage. Therefore, the number of ends in a branched molecule of glycogen will be equal to the number of branches plus the one end of the chain.

Hence, the correct answer is 'Equal to the number of branches plus one'.
