Hydrolases and Bond Hydrolysis — NEET Biology

Hydrolases are enzymes that break down various types of chemical bonds by adding water molecules (hydrolysis). NTA tests this concept because hydrolases are crucial in digestion and cellular metabolism, breaking down biomolecules like proteins, carbohydrates, and fats. Students commonly mistake hydrolases for enzymes that form bonds instead of breaking them—remember they always ADD water to cleave bonds. The key is recognizing different hydrolases by the bonds they target: peptidases break peptide bonds, lipases break ester bonds in fats, amylases break glycosidic bonds in carbohydrates. Knowing these specifics helps you match enzyme types to their substrates and predict digestion pathways correctly.
