Question: 1 / 935

What is essential for the absorption of fatty acids and glycerol molecules?

Fat droplets must be emulsified

The absorption of fatty acids and glycerol relies on the emulsification of fat droplets. Emulsification is the process by which large fat globules are broken down into smaller droplets, increasing their surface area. This is critically important because it allows pancreatic lipase, the digestive enzyme that breaks down triglycerides into fatty acids and glycerol, to more effectively act on the fats.

When emulsified, these smaller fat droplets can be more readily mixed with the aqueous environment of the intestine, facilitating their interaction with lipase. Once digested, the resulting fatty acids and glycerol can then be absorbed through the intestinal mucosa into the lymphatic system and eventually enter the bloodstream. Therefore, emulsification is the essential step that prepares fats for absorption, making it the correct choice among the options provided.
