Question

The linkage present in Lactose is ___________.

• A. α, β-1,2 glycosidic linkage
• B. α-1,4 glycosidic linkage
• C. β-1,4 glycosidic linkage
• D. α-1,4 glycosidic linkage

Hint:

Lactose, containing galactose and glucose, is connected via a β-1,4 glycosidic bond, which classifies it as a reducing sugar.

Answer 1

The Correct Option is C

Lactose, a disaccharide, is formed by linking one molecule of β-D-galactose with one molecule of D-glucose through a β-1,4 glycosidic bond. Therefore, the correct answer is (C) β-1,4 glycosidic linkage.
