<prompt> Maximum absorption of short chain fatty acids produced by bacteria occurs in theColonDuodenumJejunumIleum  <response>: A. Colon 475. Ganong 22nd 458 - Ganong 23rdShort-chain Fatty Acids in the colon SCFAs are produced in the colon and absorbed from it Absorption of long chain FA is greatest in the upper parts of the small intestine Average normal concentration of about 80 mmol L in the lumen About 60 of this total is acetate, 25 propionate, and 15 butyrate. They exert a trophic effect on the colonic epithelial cells, combat inflammation, and are absorbed in part by exchange for H, helping to maintain acid -base equilibrium. Also promote the absorption of Na Cholesterol, like the short chain fatty acids is absorbed directly into lymphatics and reconverted esterified therefrom as cholesterol esters. Its absorption requires presence of bile, fatty acids and pancreatic juice. It is mainly absorbed from the distal small intestine 276- A. K. Jain 3rd
