Question

Which of the following exhibit mutarotation?

• A. Glucose
• B. Maltose
• C. Fructose
• D. Galactose

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A Fructose
B Glucose
C Galactose
D Maltose

Mutarotation is the change in the optical rotation because of the change in the equilibrium between two anomers, when the corresponding stereocenters interconvert. Cyclic sugars show mutarotation as and anomeric forms interconvert. Glucose, Maltose, Fructose and Galactose all shows mutarotaion.
