Question

Which of the following will not show mutarotation ? (A) Maltose (B) Lactose (C) Glucose (D) Sucrose

Tardigrade Admin · Accepted Answer

Sucrose does not exhibit mutarotation because the glycosidic bond is between the anomeric carbon of glucose and anomeric carbon of fructose. Hence hemiacetal is not present in sucrose, while it is there in lactose, maltose and glucose.
