Question:

Methyl α-d-glucopyranoside is a stable compound that does not undergo mutarotation under neutral or basic conditions. However, when subjected to acidic conditions, an equilibrium is established consisting of both methyl α-d-glucopyranoside and methyl β-d-glucopyranoside. Draw a mechanism that accounts for this observation.
