Non-Reducing Sugar

Non-reducing sugars are carbohydrates that cannot be oxidized by a weak oxidizing agent because they lack a free aldehyde or ketone group. Sucrose and trehalose are examples of non-reducing sugars.

Explanation

Sucrose:
- Sucrose is a disaccharide composed of glucose and fructose.
- It does not have a free aldehyde or ketone group, making it a non-reducing sugar.

Trehalose:
- Trehalose is a disaccharide composed of two glucose molecules.
- Similar to sucrose, trehalose does not have a free aldehyde or ketone group, making it a non-reducing sugar.

Conclusion

Both (a) and (b):
- Both sucrose and trehalose are examples of non-reducing sugars because they do not contain a free aldehyde or ketone group that can be oxidized by weak oxidizing agents.
