The bond between a sugar and another molecule, usually another sugar, to create oligosaccharides. The chemical bond is formed by a condensation reaction, the hydroxyl group on the sugar reacts with the other molecule forming a glycosidic bond and releasing a molecule of water. For example, the disaccharide maltose consists of two D-glucose residues which are joined by a glycosidic bond between the alpha-anomeric form of C1 on one of the glucose molecules and the hydroxyl oxygen atom on C4 of the adjacent glucose molecule.[1]
