title: Influence of the diet on the portal and lymph transport of decanoic acid in rats. Simultaneous study of its mucosal catabolism.
abstract: The absorption route of decanoic acid, a medium chain fatty acid, infused in the intestinal lumen in the presence and absence of long chain fatty acids, has been analyzed. Ex vivo perfusion of isolated intestinal loop and intestinal lymph fistula was the technique used. Decanoic acid infused alone was essentially transported through the portal system. If infused in association with monopalmitin, oleic or palmitic acid, up to 3% of decanoic acid could be diluted in the lymph. Moreover, decanoic acid oxidation by the mucosa increased significantly with palmitic acid and in contrast decreased with oleic acid. These data show that both intestinal absorption processes and mucosal oxidation of the medium chain fatty acids are modulated by the lipid components of the diet.
