Explain mutarotation in glucose. |
| Answer» Solution :The specific ROTATION of pure `alpha` and `beta-(D)` glucose are `112^(@)` & `18.7^(@)` RESPECTIVELY. However, when pure form of any ONE of these sugars dissolved in water, slow interconversion of `alpha`-D glucose and `beta`-D glucose via open chain form until EQUILIBRIUM is established giving constant specific rotation`+ 53^(@)`. This phenomenon is called MUTAROTATION. | |
