Kinetics of adsorption of proteins at interfaces. Part I. The role of bulk diffusion in adsorption

The Role of Electrostatic Forces in Anomalous Adsorption Behavior of Phosvitin at the Air/Water Interface

“…Theoretical G versus P ele curves, calculated from Eq. [7], are shown in Fig. 10 vitin are not present in the interface.…”

“…that there is no cooperativity among phosvitin molecules Protein adsorption at interfaces is generally considered to adsorbing at the interface. However, a negative value of l be irreversible (7,9,27). However, the data in Fig.…”

“…The contribution of electrostatic repulsive forces to the surface pressure of a protein film at the air-water interface is given by the Davies equation (5) P ele Å 6.1C 1/2 [cosh sinh 01 (135/A ele C 1/2 ) 0 1], [7] where C is the concentration of equivalent electrolyte in the bulk phase, A ele (ÅA/z) is the area (in Å 2 ) per charge in the surface of the protein film, and z is the net charge of the protein. Theoretical G versus P ele curves, calculated from Eq.…”

Adsorption Dynamics of α-Lactalbumin and β-Lactoglobulin at Air–Water Interfaces

“…This property has led to their use as stabilizers in food emulsions and foams. At short times, protein adsorption has been shown to be diffusion controlled (1,2). At larger times, however, it has been shown that an adsorbing protein molecule has to overcome surface pressure as well as electrostatic energy barriers in order to anchor itself at the interface (3,4).…”

Adsorption Dynamics of Native and Alkylated Derivatives of Bovine Serum Albumin at Air–Water Interfaces

“…Buffer proteins were found to be negligible (6). Gonzalez and Mac-solutions at pH 7 and 5.5 were prepared with mono-and Ritchie measured the rate of desorption of BSA from an disodium phosphate and were used within 2 weeks after air-water interface and found that the energy barrier to de-preparation.…”
