Learning Objectives
- Summarize the steps in lipid digestion and absorption.
- Explain how lipids are used for energy and stored in the body.
Lipids are large molecules and generally are not water-soluble.
Explain the digestion of fats in the body
Like carbohydrates and protein, lipids are broken into small components for absorption. Since most of our digestive enzymes are water-based, how does the body break down fat and make it available for the various functions it must perform in the human body?
From the Mouth to the Stomach
Remember that the building blocks of lipids are triacyglycerols and phospholipids, here we will discuss how they are digested and absorbed.
The first step in the digestion of triacylglycerols and phospholipids begins in the mouth as lipids encounter saliva. Next, the physical action of chewing coupled with the action of emulsifiers enables the digestive enzymes to do their tasks.
The enzyme lingual lipase, along with a small amount of phospholipid as an emulsifier, initiates the process of digestion (Figure
