Lipase catalyzes the breakdown of which type of molecules?

Explanation:
Lipase is an enzyme that digests fats, a type of lipid. It catalyzes the hydrolysis of triglycerides into glycerol and fatty acids, a key step in fat digestion that makes them easier to absorb. In the digestive system, bile emulsifies fats to increase surface area, allowing lipase to work more efficiently. This specialization is different from enzymes that target other macromolecules: proteases break down proteins, amylases break down carbohydrates, and nucleases break down nucleic acids. So the molecule lipase acts on is fats.
