| C. |
Diffuse directly into portal circulation |
| D. |
All of the above |

Correct Answer � D Explanation |
 |
Ans. is ‘d‘ i.e., All of the above
The metabolism of short-chain fatty acids (SCFAs) and medium-chain fatty acids (MCFAs) is drastically different from long-chain fatty acids (LCFAs).
SCFAs and MCFAs do not require pancreatic lipase and bile salts for digestion but required for LCFAs digestion.
SCFAs and MCFAs are directly absorbed from the intestine into the portal circulation, whereas LCFAs are taken by lymphatics, after incorporation into chylomicrons.
SCFAs and MCFAs are oxidized by peripheral cells and are not used for storage. LCFAs are esterified with glycerol to form triacylglycerol, the storage form of lipid.
