Sugars: Dissacharides

• • When two monosaccharides join via a condensation reaction, a disacccharide is formed.
• • These monosaccharides are joined together by condensation reaction.
• • Examples of disaccharides are;

  glucose + glucose= maltose

  glucose + fructose= sucrose

  glucose + galactose= lactose
• A glycosidic bond forms between the two monosaccharides as a molecule of water is released.
• Functions of disaccharides include; Sucrose is a common table sugar, Lactose is a sugar found in milk, Lactose intolerance is a common problem where the body is unable to digest lactose.
