The functional group that best represents ketoses is
Correct answer: A. CO
- A. CO
- B. COOH
- C. HCOH
- D. HOH
Explanation
Ketoses are sugars characterized by the presence of a ketone group, represented by the carbonyl group CO. This is typically found within the carbon chain of the sugar. Therefore, Option A (CO) correctly identifies the ketone functional group characteristic of ketoses.Option B (COOH) represents a carboxyl group, which is found in carboxylic acids rather than sugars like ketoses. Option C (HCOH) is an aldehyde group, which is characteristic of aldoses, not ketoses. Finally, Option D (HOH) is simply water, which does not pertain to the classification of ketoses.

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.
