When two monosaccharides are connected by a glycosidic bond, a disaccharide is created. Disaccharides are simple sugars that are soluble in water, just like monosaccharides. Maltose, lactose, and sucrose are three typical examples.
One of the four chemical divisions of carbohydrates is the disaccharide group. Disaccharides having 12 carbon atoms, such as sucrose, lactose, and maltose, have the general formula C12H22O11.
These disaccharides differ according to atomic configurations inside the molecule. Monosaccharides are joined into double sugars through a condensation reaction, which only requires the removal of a water molecule from the functional groups.
A type of enzyme known as a disaccharidase facilitates the hydrolysis of a double sugar into its two monosaccharides.
