Explanation: 

Detailed explanation-1: -A disaccharide (also called a double sugar ) is the sugar formed when two monosaccharides (simple sugars) are joined by glycosidic linkage . Like monosaccharides, disaccharides are soluble in water. Three common examples are sucrose, lactose, and maltose.

Detailed explanation-2: -Maltose is the disaccharide which is formed by the linkage of 2 glucose residues by an alpha 1, 4 linkage. Upon hydrolysis, the glycosidic bond is broken and maltose yields 2 glucose residues.
