condensation are reversible.)<unk>  (; ) is any chemical reaction in which a molecule of water breaks one or more chemical bonds. The term is used broadly for substitution, elimination, and solvation reactions in which water is the nucleophile. Biological<unk>  is the cleavage of biomolecules a water molecule is consumed to effect the separation of a larger molecule into component parts. When a carbohydrate is broken into its component sugar molecules by<unk>  (e.g., sucrose being broken down into glucose and fructose), this is recognized as saccharification.<unk>  reactions can be the reverse of a condensation reaction in which two molecules join into a larger one and eject a water molecule. Thus<unk>  adds water to break down, whereas condensation builds up by removing water.
