Which one of the following is an example of reducing sugar?
Correct answer: C. Maltose
- A. Sucrose
- B. Starch
- C. Maltose
- D. Cellulose
Explanation
Option C is correct. Maltose is a reducing sugar because it has a free aldehyde group that can undergo oxidation, allowing it to act as a reducing agent in chemical reactions like the Benedict's test. In contrast, sucrose, starch, and cellulose do not possess free aldehyde or ketone groups due to their bonded structures, making them non-reducing sugars.

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.
