Answer #1

In the solution. three isoforms of glucose will be present-

those are-alpha D glucose-constituting about 36% , Open chain Glucose (intermediate form--present in very negligible amount) and beta-D glucose CH2OH Н- НО- Н -ОН -Н ОН К! O I H CH2OH H Н Н ОН ОН ОН н ОН a-D-glucopyranose TE н Н ОН ОН -ОН ОН Н- H CH2OH Н ОН B-D-glucopy 64 %

    Polarized light passing through a sugar solution is rotated. A polarimeter allows us to measure the size and direction of the rotation. A freshly prepared solution of alpha-D-glucose shows a specific rotation of +112 degrees. Overtime the rotation of the solution decreases and reaches an equilibrium of specific rotation of +52.5 degrees. In contrast, a freshly prepared solution of beta-D-glucose shows a specific rotation of +19 degrees. The rotation of this solution increases overtime to the same value as that...
