Lipoprotein Metabolism

Enterocytes release absorbed lipids the form of triglyceride-rich chylomicrons. These are acted upon by endothelial
cholesterol to synthesize
Bile acids are the end products of cholesterol catabolism. Cholic acid and chenodeoxycholic acid are the
primary bile acids synthesized ... Human liver synthesizes
