Fettabsorption
Fettabsorption, or fat absorption, is the process by which dietary fats are digested and absorbed in the small intestine. It primarily involves triglycerides, cholesterol, and fat-soluble vitamins A, D, E, and K. The process begins with emulsification by bile salts released from the liver and gallbladder, which increases the surface area for pancreatic enzymes.
Pancreatic triglyceride lipase hydrolyzes triglycerides into free fatty acids and monoglycerides. These products, along with bile
Chylomicrons are released basolaterally into the lymphatic system via lacteals, bypassing the liver on first pass
Most fat absorption occurs in the proximal small intestine (duodenum and jejunum). Impairments in fat absorption
