What characteristics determine whether a sugar is classified as a reducing sugar?

Reducing sugars are classified based on their ability to reduce other substances, such as Benedict's solution. This ability is determined by the presence of a free aldehyde or ketone group in the sugar molecule. If a sugar has this functional group, it is considered a reducing sugar.

What compounds should be used to prove the presence of aldehyde group in glucose molecule?

Tollens' reagent or Benedict's solution can be used to test for the presence of the aldehyde group in glucose. These reagents are able to oxidize the aldehyde group in glucose to form a colored precipitate. The appearance of a silver mirror or a red precipitate indicates the presence of the aldehyde group.
