What Monosaccharides Make up Sucrose?

The monosaccharides glucose and fructose join together to make up sucrose, which is a disaccharide. Sucrose's chemical structure contains a glucose ring and a fructose ring, which are connected by an acetal oxygen bridge. Sugar canes and sugar beets are used to manufacture sucrose through different processes.

Sucrose has the chemical formula C12H22O11. Besides sucrose, other disaccharides are maltose and lactose. Another monosaccharide is galactose.

Monosaccharides and disaccharides are types of carbohydrates. However, a third class of carbohydrate is a polysaccharide, which is made up of a long chain of three or more monosaccharides. Polysaccharides are complex carbohydrates that include starch and glycogen.
