Mechanisms for the intestinal absorption of bile acids
1968
John M. Dietschy
In this review experimental data are summarized which indicate that at least four different transport mechanisms account for net movement of bile acids across the gastrointestinal tract. These are active transport and the passive mechanisms of ionic, nonionic, and micellar diffusion.Of these four, active transport and passive nonionic diffusion are quantitatively of the greatest importance. Active transport is confined to the ileum and probably plays a dominant role in the absorption of conjugated bile acids. Passive nonionic diffusion may occur at any level of the gastrointestinal tract and probably is the major mechanism for the absorption of unconjugated bile acids.
