Which of the following carbohydrate is a reducing sugar?

Options

  1. AMaltose
  2. BGlucose
  3. CGalactose
  4. DAll of above

Correct answer

D. All of above

Step-by-step solution

A sugar is classified as a reducing sugar only if it has an open-chain form with an aldehyde group or a free hemiacetal group. Monosaccharides which contain an aldehyde group are known as aldoses, and those with a ketone group are known as ketoses. All monosaccharides are called reducing sugars.
