Protein adsorption hydrophobicity

WebbProtein adsorption is a very important aspect in many biomedical and biotechnological applications. For instance, many chromatographic separations, such as hydrophobic, … WebbSurface hydrophobicity of water-soluble proteins at 25 °C is generally low because, in folded globular proteins, hydrophobic residues are located inside the tightly folded structure. The heat treatment leading to the formation of amyloid fibers results in a significant change in the folding, and therefore the surface polarity.
