Breaking the Glycosidic Bond The glycosidic bond is broken when water is added in a hydrolysis (meaning ‘hydro’ – with water and ‘lyse’ – to break) reaction Disaccharides and polysaccharides are broken down in hydrolysis reactions Hydrolytic reactions are catalysed by enzymes, these are different to those present in condensation reactions Examples of hydrolytic reactions include the digestion of food in the alimentary tract and the breakdown of stored carbohydrates in muscle a...
