How an Enzyme Works The reaction that lysozyme catalyzes is a hydrolysis: it  adds a molecule of water to a single bond between two  adjacent sugar groups in a polysaccharide chain The reaction is energetically favorable because the free  energy of the products is lower than the intact chain However, the polysaccharide can remain for years in  water without being hydrolyzed because the energy of  activation is very high A colliding water molecule can break a bond linking two  sugars is the polysaccharide is distorted into a particular  shape – the transition state - in which the atoms around  the bond have a particular geometry and electron  distribution
