Conformation of gelatin chains in aqueous solutions: 2. A quasi-elastic light scattering study

Interactions in protein mixtures. Part I: Second virial coefficients from osmometry

“…For gelatin this value is larger with 4.5 nm for type A and 6 nm for type B. Our values are typically lower than the ones reported in literature (Eagland, Pilling, & Wheeler, 1974;Herning, Djabourov, Leblond, & Takerkart, 1991). Fig.…”

Universality and Specificity of Polymer Gels Viewed by Scattering Methods

“…76 Amis et al determined scaling laws for the collective and the slow modes mainly in the sol state of gelatin. A similar conclusion was also drawn by Herning et al 78 Structural investigations with static light scattering and SANS were carried out by Pezron et al, 79 and parameters, such as the molecular weight, the radius of gyration, and the second virial coefficient, were evaluated. Figure 22 shows the results of decomposition with the method proposed in Section 3 for gelatin gels with various concentrations studied at 10 C. The vertical shaded region denotes the gelation threshold (C gel ).…”

Brillouin light scattering from a biopolymer gel: hypersonic sound waves in gelatin

“…If we assume that the gelatin network may be treated in the same way as the aerogel network studied by Courtens et al [23], we can write oc <b " (5) In this equation Dac is the acoustical fractal dimension of the network, which is a probe of the connectivity of the network, and c$ is the spectral dimension, which defines the phonon density of states in terms of a power of co. If we use the elastic scalar prediction for the spectral dimension, 6 = 4/3, which is consistent with the results for the silica aerogels [-23], we obtain Dac = 2.…”

“…From small-angle neutron scattering experiments and static light scattering experiments the dynamic mesh size of the network has been found to be typical of the order of several nanometers [3,4]. Correlation spectroscopy reveals that two types of diffusion take place in the gel: a fast mode due to diffusion of individual gelatin coils and a slow mode due to diffusion of groups of entangled coils [5].…”
