Study Notes
Digestion of Lipids
- The first step in the digestion of triacylglycerol and phospholipids begins in the mouth.
Enzymes in Lipid Digestion
- Lingual lipase is the enzyme that initiates the process of lipid digestion in the oral cavity.
- Gastric lipase breaks down triacylglycerols into monoglycerides and fatty acids in the stomach.
Lipid Digestion in the Duodenum
- In the duodenum, lipids enter as fine droplets and mix with bile, making them water-soluble.
Importance of Lipid Breakdown
- Lipids are broken down into small components to facilitate absorption.
Lipid Characteristics
