Sucrose is a non-reducing sugar due to

Options

A1-2 linkage
B1-4 linkage
C1-5 linkage
D1-6 linkage

Correct answer

A. 1-2 linkage

Step-by-step solution

Sucrose is a non-reducing sugar due to 1, 2-glycosidic linkage between anomeric carbon atoms. Therefore, there is no free aldehyde or ketone group (reducing of group) as they are involved in glycosidic linkage.
