Specific Function of Bile Salts in Cholesterol Absorption.

Abstract

Entrance of cholesterol-4-C14 into the free cholesterol pool of mucosa and its sub-sequent transfer to the lymph requires the presence of a specific type of bile salt. This process does not require the presence of dietary fatty acid. Free cholesterol in the intestinal lumen probably complexes with bile salt which then enters the free cholesterol pool of mucosa.
