Concept introduction:
Disaccharides are carbohydrates that yield two monosaccharide molecules on hydrolysis.
Disaccharides are glycosides in which the alkoxy group attached to the anomeric carbon atom is derived from a second sugar molecule.
Maltose is made up from hydrolysis of starch.
In maltose, two
The linkage in maltose is called
The change from one anomeric form to the equilibrium mixture is accompanied by a change in optical rotation is termed as mutarotation.
Diasaccharides undergo mutarotation when dissolved in water.
The mutarotation is a slow process in aqueous solutions but can be catalyzed by either acid or base.
A base abstracts an acidic proton in the given structure.
The flow of electrons in the mechanism is shown by the curved arrows.
The open chain form of the sugar is the key intermediate in the mutarotation of disaccharides.
