The Effect of Hydroxyl Moieties and Their Oxosubstitution on Bile Acid Association Studied in Floating Monolayers

Figure 4

Compression isotherms of CDCA, DCA, HDCA, and UDCA measured on 3 M NaCl at pH = 1.2 aqueous subphase at ^°C. Increasing hydrophilicity of molecules is indicated by the arrow. Surface pressure unit is expressed in mJ/m² instead of the commonly applied mN/m.
