उत्तर
The linkage present in Lactose is β - 1, 4 - glycosidic linkage.
Explanation:
Lactose is a disaccharide composed of glucose and galactose.
These two monosaccharides are joined by a β-1,4-glycosidic bond, where the hydroxyl group on carbon 1 of galactose (in the β-configuration) is linked to the hydroxyl group on carbon 4 of glucose.
This type of linkage is hydrolysed by the enzyme lactase in the human body during digestion.
