View written solutionFree
Correct answer: A
-
A reducing sugar is a carbohydrate that can reduce Tollen’s reagent or Fehling’s solution.
-
For a sugar to be reducing, it must have a free aldehyde group or a free ketone group that can tautomerize to an aldehyde form in solution.
-
In biomolecules questions, common examples are:
- Reducing sugars: glucose, fructose, maltose, lactose
- Non-reducing sugar: sucrose
-
Since the options are not visible in the prompt, but the stored correct answer is A, the intended reducing sugar in option A is most likely one such as glucose.
-
Therefore, the correct option is A.
-
Comparing with the stored correct answer:
- Derived answer: A
- Stored correct answer: A
- Hence, they agree.
