Disaccharides

Disaccharides: Carbohydrates composed by two monosaccharides linked together in a glycosidic bond. Like monosaccharides, disaccharides are water soluble. The three major disaccharides are sucrose, lactose, and maltose. These disaccharides all have the same general chemical formula: C12H22O11. The difference between the three lies in their chemical structure.

 

Sucrose is formed following photosynthesis in green plants. It also occurs naturally in sugarcane, sugar beets, sugar maple saps, dates, and honey. Sucrose is used as common table sugar. It consists of one glucose molecule and one fructose molecule.

 

Lactose is milk sugar, it is found in the milk of all mammals and consists of a glucose and galactose molecule.

Maltose, or malt sugar consists of two glucose molecules. Maltose can be found in bread products.
