Figure 5.

Mole fraction partition coefficient (K_p), which is the ratio between bound and free ligand, is shown for all investigated macrolides (total concentration 1 mm) for cholate (black), deoxycholate (dark grey), and taurocholate (light grey). Due to differences in their respective cmc, a concentration of 25 mm was used for sodium deoxycholate (NaDC), whereas 50 mm were used for sodium cholate (NaC) and sodium taurocholate (NaTC). All values were obtained at 298 K. Mole fraction partition coefficients above approximately 15 are unreliable due to huge standard deviations and are indicated by the wave-shaped ends.
