Absorption of long-chain fatty acids
After digestion, how do long-chain fatty acids reach the bloodstream?
Answer A: explanation for every choice
A
Correct. Enterocytes reassemble triglycerides into chylomicrons, which are too large for capillaries and enter lymphatic lacteals.
B
Short- and medium-chain fatty acids enter the portal blood directly. Long-chain ones don't.
C
Albumin carries fatty acids in the blood, not inside enterocytes.
D
Fatty acids are not converted to glucose.
TakeawayLong-chain fats: chylomicrons → lacteals → lymph → blood.
