Disaccharide Definition:

Carbohydrates comprised of two monosaccharide units joined via a glycosidic linkage between the anomeric carbon of one monosaccharide and a hydroxyl group of the other monosaccharide.

Disaccharide Explained:

The formation of Disaccharides is the result of the condensation of two simple sugars. When condensation takes place the loss of water is seen, two OH from both sugars react and form an Oxygen bridge. One of the OH group is attached to an anomeric carbon. (Carbon that is bonded to two oxygen bonds)
