Question: All aldoses exhibit mutarotation. For example, -D-galactopyranose has []D = + 150.7, and -D-galactopyranose has []D = + 52.8. If either anomer is dissolved in

All aldoses exhibit mutarotation. For example, α-D-galactopyranose has [α]D = + 150.7, and β-D-galactopyranose has [α]D = + 52.8. If either anomer is dissolved in water and allowed to reach equilibrium, the specific rotation of the solution is + 80.2. What arc the percentages of each anomer at equilibrium? Draw the pyranose forms of both anomers.
