Disaccharides Hydrolysis of Sucrose

Disaccharides are O-glycosides in which the hydroxyl group attached to the anomeric carbon atom of one monosaccharide is replaced with a hydroxyl group of See more on Maltose another monosaccharide, thereby forming a cyclic acetal. For example, maltose (11) 

Fructose is the sweetest common sugar, being about twice as sweet as sucrose consequently, invert sugar is sweeter than sucrose. The enzyme invertase, which bees use in making honey, accomplishes the same chemical result as does the acid-catalyzed hydrolysis of sucrose. 

In the experiment in this section, you will examine the acid-catalyzed hydrolysis of sucrose to give a mixture of D-glucose and D-fructose and monitor the consequent change in the specific rotation that occurs using a polarimeter.
