Aqueous RAFT Synthesis of Low Molecular Weight Anionic Polymers for Determination of Structure/Binding Interactions with Gliadin.

ABSTRACT: Gliadin, a component of gluten and a known epitope, is implicated in celiac disease (CeD) and results in an inflammatory response in CeD patients when consumed. Acrylamide-based polyelectrolytes are employed as models to determine the effect of molecular weight and pendent group on non-covalent interaction modes with gliadin in vitro. Poly(sodium 2-acrylamido-2-methylpropane sulfonate) and poly(sodium 3-methylpropyl-3-butanoate) are synthesized via aqueous reversible addition fragmentation chain transfer (aRAFT) polymerization and characterized by gel permeation chromatography-multiangle laser light scattering. The polymer/gliadin blends are examined via circular dichroism, zeta potential measurements, 8-anilinonaphthalene-1-sulfonic acid fluorescence spectroscopy, and dynamic light scatte
