Which enzyme breaks down dietary fats?

The enzyme that breaks down dietary fats is lipase. Lipase is specifically responsible for the hydrolysis of triglycerides, which are the main constituents of dietary fats. When you consume fats, lipase converts them into their simpler components, fatty acids and glycerol, enabling the body to absorb and utilize these nutrients effectively.

Amylase, on the other hand, is an enzyme that breaks down carbohydrates, not fats. Protease is responsible for the breakdown of proteins, while lactase is an enzyme that breaks down lactose, the sugar found in milk. Each of these enzymes has a specific function related to different types of macromolecules, making lipase the correct choice for the breakdown of dietary fats.
