The adsorption of proteins to gas-liquid interfaces

β-Casein Bilayer Adsorption at the Solution/Air Interface: Experimental Evidences and Theoretical Description

“…To explain the adsorption increase in the concentration range above 5 × 10 −7 mol/l, multilayer models have been proposed (4,8). Guzman et al (8) compared only the -c isotherm of Graham and Phillips with the theoretical model.…”

“…Theoretical adsorption isotherms, which match the experimental data in (2), were derived by Guzman et al (8) and Douillard and Lefebvre (9). In (4) a 3-dimensional scaling model of the surface layer was used to describe the adsorption of β-casein within the range of 3 to 6 mg/m 2 .…”

Structural Stability Effects on Adsorption of Bacteriophage T4 Lysozyme to Colloidal Silica

“…In order to compare rate constants based of surface coverage. A dependence on surface concentration for adsorption rate constants has been proposed by Guzman on CD data to adsorption kinetics measured with ellipsometry, G max was defined as 0.10 mg/1.64 m 2 , the maximum adsorbed et al (14) in terms of activation energies for adsorption Table 2. and and desorption.…”

Estimativa de Isotermas de Adsorção Gás-Líquido Usando a Abordagem de Problema Inverso

“…Um modelo que permite caracterizar com muita precisão a depleção de proteínas como BSA (Albumina Bovina), Lysozima e β-Caseína, 6) onde Γ 1 e Γ 2 são as concentrações superfíciais em excesso da primeira e da segunda camada respectivamente, eâ, λ, K 1 e K 2 são coeficientes da isoterma. Esta curva correspondeà modelagem termodinâmica desenvolvida por Guzman et al [16], representando 2 camadas de adsorção. A primeira camadaé equivalenteà isoterma de Langmuir, podendo saturar, enquanto a segunda camada não apresenta saturação.…”
