In order to break apart a polysaccharide into disaccharides, what type of reaction needs to occur?

Question

Quizplus · Accepted Answer

Hydrolysis reactions add water to break glycosidic bonds between the monomers in a polysaccharide.
Disaccharides are formed by the condensation reactions of two simple sugar molecules coming together. Two OH groups, one from each sugar molecule, come together and form an oxygen bridge between.
There is no such thing as a "glycosidic reaction" but rather a glycosidic bond forms by a condensation reaction, which means that one water molecule is produced during formation of a glycosid.
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species.
