What is the main function of lipase?

Lipase plays a crucial role in the digestive system by being the primary enzyme responsible for the breakdown of fats (lipids). This enzyme catalyzes the hydrolysis of triglycerides into glycerol and free fatty acids, making fats more accessible for absorption in the intestines. Lipase works primarily in the small intestine, where the presence of bile salts facilitates the emulsification of fats, increasing the surface area for lipase action.

Fats are important macronutrients, and their digestion is a vital process for the absorption of fat-soluble vitamins (A, D, E, and K) and providing energy to the body. Without lipase, the body would struggle to effectively digest and utilize dietary fats, impacting overall nutrition and energy levels.

In the context of this question, recognizing that lipase specifically targets fats helps clarify its unique function compared to other digestive enzymes that focus on proteins or carbohydrates.
