What is Disaccharide?
A disaccharide (also called a double sugar or biose) 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 (table sugar, cane sugar, beet sugar, or saccharose), lactose (milk sugar), and maltose (malt sugar).
