Summary

Monolayers of various proteins were studied at airwater interface. An equation of state of the virial type, as developed byM. L. Huggins, was applied to the surface pressure-area measurements.

It was found that theHuggins equation based on statistical thermodynamics was applicable to the proteins. From this treatment of the results, the degree of submersion of protein could be determined, which was found to be dependent on the degree of unfolding of the protein at the interface.
