Monolayers were spread from an Agla micrometer syringe. Mixed monolayers consisted of 0.045 mg gliadin and 0.005 mg surfactant. For the penetration studies 5 X 10 4 mg quantities of surfactants were injected with a Hamilton microliter syringe under gliadin monolayers (5 X... 

Monolayer techniques have been used with much success to study the interaction of proteins with surfactants (11, 12, 13), ions and lipids (14), and other proteins (15). This paper investigates, through well-established procedures, the surface chemistry of monolayers of a major component of heterogeneous wheat gluten protein, gliadin, and explores these interactions with various surface-active agents.

Compression Isotherms. The 7r-A compression isotherms of gliadin and the six mixed monolayers of gliadin and surfactants are in Figures 3 and 4. The abscissa in both figures has been moved to the right by 0.2 m2/mg for successive curves to avoid confusion. All isotherms had the same approximate shape no collapse was observed even at surface pressures of 27 dynes/cm.
