The structure of model gluten protein gels prepared in ethanol/water is investigated by small angle X-ray (SAXS) and neutrons (SANS) scattering. We show that gluten gels display radically different SAXS and SANS profiles when the solvent is (at least partially) deuterated.
A new hydrostatic pressure cell designed for small-angle neutron scattering (SANS) and
quasi-elastic neutron scattering (QENS) experiments on biomolecular solutions has been
developed at the Laboratoire Léon Brillouin. SANS and QENS experiments on
bovine pancreatic trypsin inhibitor (BPTI), a small protein, have been performed
and show us that this pressure cell is well adapted to this kind of experiments.
Interesting results about the influence of pressure (1–6200 bar) on structure and dynamics
of BPTI have been obtained.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
