B 1-4 Glycosidic linkage is found in
Correct answer: B. Lactose
- A. Sucrose
- B. Lactose
- C. Maltose
- D. Amylose
Explanation
Lactose, a disaccharide composed of glucose and galactose, contains a beta-1,4-glycosidic linkage. In this linkage, the hydroxyl group (-OH) on carbon 1 of glucose is connected to the hydroxyl group on carbon 4 of galactose. This beta configuration means that the oxygen atom involved in the bond formation is below the plane of the ring in the glucose molecule and above the plane in the galactose molecule. Also its a bond between beta glucose and beta galactose.

About Carbohydrates
Carbohydrates are organic compounds classified as monosaccharides, disaccharides and polysaccharides according to their structure and hydrolysis products. The topic covers glycosidic bonds, glucose and fructose, sucrose, lactose and maltose, starch, glycogen and cellulose, along with their roles in energy storage, structural support and food tests.
