Description

Lipid metabolism is a complex process that involves multiple steps involving the dietary intake of lipids (exogenous) or the production of lipids within the body (endogenous) to degradation or transformation (catabolism) into several lipid-containing structures in the body. A brief description of metabolism related to fatty acids and cholesterol is provided below.

The dietary fat in the form of triacylglycerol (TAG), cholesterol, cholesteryl esters, and free fatty acids is absorbed by the intestine after going through various steps during digestion from mouth to intestine.

Fatty acids, once absorbed from intestine, are activated in the intestinal wall and eventually resynthesize the TAG. Some of the shorter-chain fatty acids go to the...
