A disaccharide is a sugar (a carbohydrate) composed of two monosaccharides.

Chemistry[edit | edit source]

The two monosaccharides are bonded via a condensation reaction. This bond can be between the 1-, 4-, or 6-carbon on each component monosaccharide. So, even if both component sugars are the same (e.g., glucose), different bond combinations result in disaccharides with different chemical and physical properties.

Depending on the monosaccharide constituents, disaccharides are sometimes crystalline, sometimes water-soluble, and sometimes sweet-tasting.

Common disaccharides[edit | edit source]


Maltose and cellobiose are hydrolysis products of the polysaccharides, starch and cellulose, respectively.
