| mutarotation | <chemistry> Name given to the phenomenon that occurs when glucose is dissolved in water. There is an equilibrium that is formed between the open-chain form and the alpha and beta pyranose forms. The beta is the most stable conformation because it puts the -OH in an equatorial position and thus most of the glucose in the aqueous solution is in the beta form. (09 Jan 1998) |

| mutarotation |
a change in the optical activity of a freshly prepared solution of a pure compound that occurs because of the formation of diastereoisomers of the original compound having different optical activity, e.g., the equilibration of the α and β anomers of glucose.
