-Most fat absorption takes place in the duodenum or jejunum –
micelles carry monoglycerides and free fatty acids to the brush
border where they diffuse into enterocytes.
Absorption
-Bile salts are absorbed in the ileum (enterohepatic circulation).
-Once in the enterocytes, monoglycerides and free fatty acids are
reformed into triglycerides.
-The triglycerides, cholesterol, phospholipids, and protein carriers
form LIPOPROTEIN.
-These lipoproteins leave the cell, they become CHYLOMICRONS
and enter the lymph system MCTs.
-Short-chain fatty acids and glycerol are absorbed directly into
bloodstream. They do not enter the lymph system.
