What do disaccharides, such as sucrose, and polysaccharides, such as starch, have in common?

Polysaccharides and disaccharides are carbohydrates made of simple sugars such as glucose. Disaccharides are carbohydrates made up of two simple sugars by a process of condensation while polysaccharides are carbohydrates similar to disaccharides that consist of three or more molecules and are joined by a chemical link called glycosidic bonds. Sucrose is a disaccharide made up of simple sugars glucose and fructose, while starch is a polysaccharides consisting of a large number of glucose units joined by glycosidic bonds.
