Question

Among the following, the incorrect statement is :

• A. Maltose and lactose has 1, 4-glycosidic linkage
• B. Sucrose and amylose has 1, 2-glycosidic linkage
• C. Cellulose and amylose has 1, 4-glycosidic linkage
• D. Lactose contains $\beta$-D-galactose and $\beta$-D-glucose

Answer 1

Answer: (B)

The two hexoses in sucrose have a glycosidic linkage that involves $C1$ of gloucose and $C2$ of fructose.



Amylose typically consistance of more than 1000 D- glucopyranoside units connection in $\alpha$ linkages between $C1$ of one unit and $C4$ of the next
