Among the following the incorrect statement is -

1. Cellulose and amylase have 1,4-glycosidic linkage
2. Lactose contains β-D-galactose and D-glucose
3. Maltose and lactose have 1,4-glycosidic linkage
4. Sucrose and amylase have 1,2-glycosidic linkage

Correct answer: Sucrose and amylase have 1,2-glycosidic linkage

Solution

The statement is incorrect because sucrose is a disaccharide formed from glucose and fructose linked by a 1,2-glycosidic bond, while amylase is an enzyme that breaks down starch and does not contain any glycosidic linkages.
