-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.

-Bile salts are absorbed in the ileum (enterohepatic circulation).
-Once in the enterocytes, monoglycerides and free fatty
acids are reformed into new triglycerides.
-The triglycerides, cholesterol, phospholipids, and protein
carriers form LIPOPROTEIN.

-These lipoproteins leave the cell, and enter the  lymph
system. MCTs (medium chain triglycerides).

-Short-chainfatty acids and glycerol are absorbed directly
into bloodstream. They do not enter the lymph system.
