Answer
Sucrose is made up of atoms of carbon, oxygen and hydrogen. The bonds between these non-metallic atoms are covalent bonds in which electrons are shared rather than donated and accepted. However, these covalent bonds are slightly polar: for example, in hydrogen-oxygen bonds the oxygen atom nucleus attracts the electrons more powerfully than does the hydrogen atom nuclei.. Consequently, the oxygen end of such a bond is more electro-negative that the hydrogen ends. The polar end of the sucrose covalent bonds attract the polar water molecules and this facilitates solution of the disaccharide sugar.

Th glycosidic linkage(bond) between fructose and glucose is also a covalent bond. In all these cases the non-metallic atoms share electrons in trying to achieve noble gas configurations.
