Which feature is not characteristic of cellulose?
Correct answer: C. 1-6 glycosidic bonds
- A. β-glucose molecules
- B. Fibrillar structure
- C. 1-6 glycosidic bonds
- D. Hydrogen bonds
Explanation
The correct answer is Option C: 1-6 glycosidic bonds. Cellulose is composed of β-glucose molecules linked by 1-4 glycosidic bonds, forming straight chains. Unlike cellulose, polysaccharides like starch and glycogen contain 1-6 glycosidic bonds, which result in branching. Cellulose's structure includes hydrogen bonds that hold the chains together in a fibrillar arrangement, providing strength and rigidity. Therefore, the presence of 1-6 glycosidic bonds is not characteristic of cellulose.

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.
