Counter‐Ion Binding by Bile Acid Solutions
Natarajan Rajagopalan, Siegfried Lindenbaum – 1 September 1984 – The binding of Ca2+ to micelles of glycine and taurine bile acid conjugates was studied using a Ca2+−‐specific electrode. An investigation of the effect of buffer concentration, pH, added electrolyte and lecithin was also performed. The results indicate that the binding of Ca2+ to bile salt micelles is dependent on the number of hydroxyl groups on the steroid nucleus and on the nature of the head conjugating group, namely, glycine or taurine.
