Q: Which of the following carbohydrates is a reducing sugar?
Solution: Maltose is a reducing sugar because it has a free aldehyde or ketone group, while sucrose does not.
Steps: 5
Step 1: Understand what a reducing sugar is. A reducing sugar is a carbohydrate that can donate electrons to another molecule, usually because it has a free aldehyde or ketone group.
Step 2: Identify the carbohydrates in the question. The question mentions maltose and sucrose.
Step 3: Check the structure of maltose. Maltose has a free aldehyde group, which means it can act as a reducing sugar.
Step 4: Check the structure of sucrose. Sucrose does not have a free aldehyde or ketone group, so it cannot act as a reducing sugar.
Step 5: Conclude that maltose is a reducing sugar because it has a free aldehyde group, while sucrose is not a reducing sugar.
