Non-Reducing Sugar
- Sugars are categorized based on their ability to act as reducing agents. Reducing sugars contain free aldehyde or ketone groups that can react with oxidizing agents.
- Non-reducing sugars do not have free aldehyde or ketone groups due to their glycosidic bonds. Thus, they cannot act as reducing agents.
EXPLANATION:
- Maltose (option 1) is a reducing sugar because it has a free aldehyde group.
- Sucrose (option 2) is a non-reducing sugar because the glycosidic bond between glucose and fructose blocks the free aldehyde or ketone groups.
- Lactose (option 3) is a reducing sugar because it has a free aldehyde group.
- Glucose (option 4) is a reducing sugar because it has a free aldehyde group.
Therefore, the correct answer is option 2, Sucrose.
