The monomer molecules may … WitrynaHydrolysis is a chemical reaction during which polymers (large molecules) break down into monomers (small molecules).. During hydrolysis, covalent bonds between monomers break, which allows for the breaking down of polymers. Bonds are broken down using water.Hydro literally means 'water', and - lysis stands for 'to unbind'. ion marius tatomir wikipedia
