Bile salts at the air-water interface: Adsorption and desorption

- Dynamic adsorption curves reveal higher adsorption rates of NaTC than NaGDC.
- Adsorption isotherms reveal different conformational regimes for NaTC and one conformational regime NaGDC.
- The different conformational regimes imply different dilatational response: two maxima of the dilatational modulus for NaTC and one maximum for NaGDC.
- Desorption profile of NaGDC shows higher desorption ratio than NaTC.
- Conformational regimes suggest surface complexation.
