Chemistry Question on Biomolecules
Which of the following will not show mutarotation?
A
Maltose
B
Lactose
C
Glucose
D
Sucrose
Answer
Sucrose
Explanation
Solution
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.
So, the correct option is (D): Sucrose.
