Enzyme Adsorption
EditEnzyme adsorption is the accumulation of enzyme molecules at a material surface through noncovalent interactions between the protein and the interface. Adsorbed enzymes form a carrier-associated catalytic preparation in which the support retains protein during reaction and separation [1][2]. Surface area, pore architecture, and protein–surface contacts determine how enzyme molecules occupy the material and which portions remain exposed to solution [3]. Hydrophobic supports can bind lipases through interfacial activation, stabilizing a surface-associated conformation with an accessible catalytic region. Changes in solvent composition or the presence of detergents can release the adsorbed enzyme [4]. Adsorption therefore produces a reversible association. Enzyme loading, the proportion of activity retained, and accessibility of substrates describe distinct properties of the resulting immobilized preparation [5].
