				   What Is Mutarotation? Give Example And Structure

5 years ago


Answers : (4)


Mutarotation is the change in the optical rotation that occurs by epimerization (that is the change in the equilibrium between two epimers, when the corresponding stereocentersinterconverted).

Cyclic sugars show mutarotation as α and β anomeric forms are interconvert. The optical rotation of the solution depends on the optical rotation of each anomer and their ratio in the solution.

										Mutarotation has to do with how a molecule rotates the plane of light. For example, alpha glucose has theOH group at a different position than beta glucose. (See link for diagram). This angle can be measured using a Polarimeter.Mutarotation is the term given to the change in the specific rotation of plane polarized light, when it is passed through an aldohexose (monosaccharides with six carbon atoms and H-C=O group). Mutarotation refers to the conversion of a pure anomer of a hemiacetal carbohydrate to an equilibrium mixture of two anomers.As the name suggests, it is the change in rotation ("Muta" means"Change").Plane polarized light is obtained by passing ordinary light through a nicol prism.During mutarotation, either α or β forms keep changing into the chainstructure periodically to and fro.Mutarotation also refers to the interconversion between the α and β anomers. However it must be converted to the open chain structure first before it can change conformation to the α or β position.
