The aggregation numbers (Ag#) of free and conjugated di- and trihydroxy bile salts were studied by equilibrium ultracentrifugation and light scattering. The effect of concentration, counterion concentration, pH, temperature, and urea are shown. All trihydroxy bile salts form very small micelles (Ag#
