Mutarotation is not exhibited by:
(+) Sucrose
(+) Lactose
(+) Maltose
(–) Fructose
(+) sucrose does not show mutarotation.
Mutarotation is shown by the saccharides which have free OH group at the anomeric carbon. In sucrose, due to the formation of a glycosidic bond between the anomeric carbons on glucose and fructose, the availability of the hydroxyl group is eliminated. Hence, it does not undergo
mutarotation.
