Hydrolases are enzymes that catalyze hydrolysis reactions, breaking bonds by adding water. This allows them to digest biopolymers such as proteins, nucleic acids, carbohydrates, and fats into smaller units like amino acids, nucleotides, sugars, and fatty acids. Examples include proteases that cut peptide bonds in proteins, amylases that cleave starches, lipases that split fats, and nucleases that digest nucleic acids. In contrast, other enzyme classes perform different tasks—oxidoreductases deal with oxidation-reduction, transferases move groups like phosphates, and ligases build new bonds. The key idea is that hydrolases use water to break bonds in large biomolecules, which is why this description fits them best.
