Bile salts and calcium absorption.
1. The study of the effect of bile salts on enhancing calcium absorption in the rachitic chick has been extended to bile salts not present in chick bile, e.g. glycine conjugates and bile alcohol sulphates. 2. Bile and bile salts cause an increase in calcium absorption from sparingly soluble calcium hydrogen phosphate when compared with a suspension of calcium hydrogen phosphate in saline. 3. If...
متن کاملBile salts and fat absorption.
There has been a recent resurgence of interest in bile salt metabolism. Normally the body contains about 3 g. of bile salts. These comprise conjugates of cholic acid and chenodesoxycholic acid. The free acids are derived from the oxidation of cholesterol in the liver and once formed are conjugated with either taurine or glycine, after which they are secreted into the bile and so enter the small...
متن کاملAbsorption-Enhancing Effects of Bile Salts.
Bile salts are ionic amphiphilic compounds with a steroid skeleton. Among the most important physiological properties of bile salts are lipid transport by solubilization and transport of some drugs through hydrophobic barriers. Bile salts have been extensively studied to enhance transepithelial permeability for different marker molecules and drugs. They readily agglomerate at concentrations abo...
متن کاملBacteria, bile salts, and intestinal monosaccharide malabsorption.
Intestinal monosaccharide transport was studied in a series of rats with a self-filling jejunal blind loop using 3mM arbutin (p-hydroxyphenyl-B-glucoside) or 1mM D-fructose as substrate in vitro and 10 mM arbutin or 5mM D-fructose in vivo. These results were compared with changes in the bacterial flora and state of conjugation of intraluminal bile salts in those animals. Observations were also ...
متن کاملVitamin D-3 intestinal absorption in vivo: influence of fatty acids, bile salts, and perfusate pH
Intestinal absorption of vitamin D-3 in physiological concentrations was studied in the live unanaesthetised rat. In both the jejunum and the ileum a linear relationship was found between the absorption rate of the vitamin and its intraluminal concentration. Increasing the sodium taurocholate concentration in the perfusate above 5 mM did not change ileal absorption rate but did decrease jejunal...
