The disaccharides maltose and sucrose
A disaccharide is any of a group of sugars the molecules of which are derived by the condensation of two monosaccharide molecules so that they are connected by an oxygen bridge. Upon hydrolysis, disaccharides yield the corresponding monosaccharides. The disaccharide sucrose (table sugar), for example, consists of one glucose molecule and one fructose molecule bound together. Other important disaccharides include lactose and maltose.
