We study the equilibrium liquid structure and dynamics of dilute and concentrated bovine eye lens α-crystallin solutions, using small-angle X-ray scattering, static and dynamic light scattering, viscometry, molecular dynamics simulations, and mode-coupling theory. We find that a polydisperse Percus–Yevick hard-sphere liquid-structure model accurately reproduces both static light scattering...

Structure of heat-induced β-lactoglobulin aggregates and their complexes with sodium-sodecyl sulfate

Jung, Jin-Mi ; Savin, Gabriela ; Pouzot, Matthieu ; Schmitt, Christophe ; Mezzenga, Raffaele

In: Biomacromolecules, 2008, vol. 9, no. 9, p. 2477–2486

We report on the conformation of heat-induced bovine β-lactoglobulin (βlg) aggregates prepared at different pH conditions, and their complexes with model anionic surfactants such as sodium dodecyl sulfate (SDS). The investigation was carried out by combining a wide range of techniques such as ultra small angle light scattering, static and dynamic light scattering, small angle neutron...
