胆汁酸结合物被吸附到谷物纤维上。胆汁酸结合物与胆固醇结合成胶束，作为胶束可逆地吸附到纤维上。用单甘酯将胆汁酸结合物修饰成胶束，在一定程度上抑制了胆汁酸结合物的吸附。如果将脂肪酸、甘油单酯和胆汁酸共轭物混合胶束暴露于谷物纤维，则胆汁酸对纤维的吸附减少。吸附减弱的程度受脂肪酸浓度、链长和不饱和度的影响。这表明胆汁酸结合物在空肠中最低限度地吸附到纤维上，但在盲肠中的解结合和脱羟基作用有利于吸附。
Bile acid conjugates are adsorbed to cereal fiber. Bile acid conjugates incorporated into micelles with cholesterol are reversibly adsorbed as micelles on to the fiber. Incorporating bile acid conjugates into micelles with monoglycerides somewhat depresses adsorption of bile acid conjugate. If fatty acids, monoglycerides, and bile acid conjugate mixed micelles are exposed to cereal fiber, then adsorption of bile acids to the fiber is diminished. The extent to which the adsorption is diminished is affected by the fatty acid concentration, chain length, and unsaturation. This suggests that bile acid conjugates are minimally adsorbed to fiber in the jejunum but deconjugation and dehydroxylation as in the cecum favors adsorption.
