Answer :
Two simple sugars combine through a condensation reaction to form a disaccharide, linked by a glycosidic bond, resulting in compounds like sucrose.
When two simple sugars are covalently linked together, a disaccharide is formed. This occurs through a condensation reaction where a water molecule is released. For instance, when a glucose molecule and a fructose molecule combine, they form sucrose, which is the most common disaccharide.
The covalent bond that holds the two monosaccharides together is called a glycosidic bond or glycosidic linkage, and it can exist in either alpha or beta configurations depending on the orientation of the hydroxyl groups involved in the bond formation.
