Polymeric Assembly of Gluten Proteins in an Aqueous Ethanol Solvent [PDF]
J. Phys. Chem. B 2014, 118, 11065, 2014 The supramolecular organization of wheat gluten proteins is largely unknown due to the intrinsic complexity of this family of proteins and their insolubility in water. We fractionate gluten in a water/ethanol (50/50 v/v) and obtain a protein extract which is depleted in gliadin, the monomeric part of wheat gluten proteins, and enriched in glutenin, the
