					 Disaccharide molecules that contain β(1 → 4) glycosidic linkage are
- 
                        - sucrose and maltose 
- sucrose and isomaltose 
- maltose and isomaltose 
- lactose and cellobiose
 
Correct Option: D
Glycosidic bond or glycosidic linkage is a type of covalent bond that joins a carbohydrate (sugar) molecule to another group, which may or may not be another carbohydrate. Lactose (β-D-galactopyranosyl (1→ 4) D-glucopyranose) and cellobiose (β-D-glucopyranosyl (1→4) D-glucopyranose) are disaccharides whose monomeric units are connected by β(1→ 4) glycosidic bonds.
