Disaccharides

• Synthesising


  When an (OH) group on two separate monosaccharides goes through a condensation reaction to form a molecule of water (H2O) and a glyosidic bond between the two Monosaccharides both bonded to the remaining oxygen forming a disaccharide
• Sucrose


  .Glucose + Fructose = Sucrose

  .Mass produced sugar in sugarcane, sugar beets, maple sap, dates and honey
• Maltose


  .A glucose + A glucose = Maltose

  .Beer, bread, cereals, potatoes
• Lactose


  .Galactose + A glucose = Lactose

  .Found in dairy products
• Summary


  Lactose=Galactose+Aglucose

  Maltose=Aglucose+Aglucose

  Sucrose=Aglucose+Fructose
