MCQ
An example of non-reducing sugar is
- ✓Cane sugar
- BFructose
- CLactose
- DCellobiose
✓
Answer
Correct option: A.
Cane sugar
a
There is no free aldehydic group present in cane sugar.Due to glycosidic linkage, the aldehydic group is no more free. While in others, there is a free aldehydic/ketonic group present. Even if ketonic group is present, it isomerizes to aldehydic group. So, cane sugar is a non reducing sugar.Note: Sucrose and cane sugar are one and the same.
