Which is TRUE Regarding Chylomicrons

Question

Which is TRUE regarding chylomicrons?
A)They readily cross the plasma membrane of adipocytes.
B)They are converted to monoglycerides and fatty acids by an enzyme inside muscle cells.
C)They are converted to monoglycerides and fatty acids by an enzyme found inside capillaries.
D)They are formed in the lumen of the GI tract by the action of bile salts.
E)They are too large to enter lacteals.

Accepted Answer

Chylomicrons are converted to monoglycerides and fatty acids by lipoprotein lipase, an enzyme found on the endothelial cells lining the capillaries, not inside muscle cells or adipocytes. This process facilitates the uptake of fatty acids by tissues such as muscle and adipose tissue.
