In glycogen, what kind of linkage is found between adjacent glucose molecules?
Correct answer: C. Both 1,4 and 1,6
- A. 1,4
- B. 1,6
- C. Both 1,4 and 1,6
- D. 1,2
Explanation
Glycogen is a highly branched polysaccharide that serves as a form of energy storage in animals and fungi. It is composed of glucose molecules linked together primarily by 1,4-glycosidic bonds, which form the linear chains. Additionally, 1,6-glycosidic bonds are present at the branch points, occurring approximately every 10 glucose units along the linear chain. Therefore, glycogen contains both types of linkages. Options A and B highlight only one type of linkage each, which is incorrect, and Option D refers to a linkage not found in glycogen. The correct answer is Option C: 'Both.'

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
