Which one given below is a non`-` reducing sugar ?

A

Sucrose

B

Maltose

C

Lactose

D

Glucose

Text Solution

Verified by Experts

The correct Answer is:
A
Sucrose is a non-reducing sugar because the two monosaccharide units (glucose and fructose) are linked through their reducing centres i.e. `C_(1) - alpha` of glucose is connected to `C_(2) - beta` of fructose. Consequently both the monosaccaaride units exist in acetal form.
