hydrolysis -
a chemical reaction in which water reacts with a compound to produce other compounds; involves the splitting of a bond and the addition of the hydrogen cation and the hydroxide anion from the water
chemical reaction,
reaction (chemistry) a process in which one or more substances are changed into others; "there was a chemical reaction of the lime with the ground water"
hydrolysis -
The degradation of certain biopolymers proteins, complex sugars by the chemical process that results in smaller polymers or monomers.
Wikipedia
Hydrolysis is a chemical reaction during which molecules of water (H2O) are split into hydrogen cations (H, conventionally referred to as protons) and hydroxide anions (OH) in the process of a chemical mechanism). It is the type of reaction that is used to break down certain polymers, especially those made by step-growth polymerization. Such polymer degradation is usually catalysed by either acid, e.g.
