The example of polyhydroxy ketone is:
Correct answer: C. Dihydroxyacetone
- A. Glucose
- B. Glyceraldehyde
- C. Dihydroxyacetone
- D. Ribose
Explanation
Dihydroxyacetone is the correct answer because it is a ketose sugar, meaning it contains a ketone functional group. This categorizes it as a polyhydroxy ketone. In contrast, the other options are aldoses, which have aldehyde groups instead of ketone groups. This structural difference is key in differentiating between aldoses and ketoses.
