Chapter 19.SE, Problem 52MP

Interpretation Introduction

Interpretation:

A mechanism for the isomerization of α- glucose when dissolved in water into β-glucose is to be proposed.

Concept introduction:

Free rotation is possible in C-O single bonds. The glucopyranose ring in α- glucose is first cleaved followed by the rotation of C-O bond and the subsequent ring closure leads to the formation of β-glucose.

To propose:

A mechanism for the isomerization of α- glucose when dissolved in water into β-glucose.
