which one of the follwing statment abt. the absorption of lipids from intestine is correct?
a)dietary triacyglycerol is partially hydrolyzed and absorbed as free fatty acids and monoacylglycerol
b)dietary triacylgyl. must be completely hydrolyzed to free fatty acids and glycerol before absorption
c)release of fatty acids from triacylglycerol in intestine is inhibited by bile salts
d) fatty acids that contain ten carbons or less are absorbed and enter the circulation primarily via the lymphatic system
e) formation of chylomicrons does not require protein synthesis in intestinal mucosa

Answer is AAA...Pancreatic lipase hydrolyze dietary triacylglycerol primarily to 2-monoacylglycerol plus two fatty acids. these products of hydrolysis can be absorbed by the intestinal mucosal cells. Bile cells do not inhibit release of fatty acids from triacylglycerol, but rather are necessary for proper solubilization and hydrolysis of dietary triacylglycerol in small intestine. small and medium chain length fatty acids enter the portal circulation after absorption from small intestine, and synthesis of apolipoproteins, especially B-48 is essential for the assembly and secretions of chylomicrons.
