Structure and Morphology of Wheat Gluten Films: From Polymeric Protein Aggregates toward Superstructure Arrangements
(2011) In Biomacromolecules 12 (5)(Online March 24, 2011). p.1438-1448- Abstract
- Evaluation of structure and morphology of extruded wheat
gluten (WG) films showedWGprotein assemblies elucidated on a range of
length scales from nano (4.4 Å and 9 to 10 Å, up to 70 Å) to micro (10 μm).
The presence of NaOH in WG films induced a tetragonal structure with
unit cell parameters, a = 51.85 Å and c = 40.65 Å, whereasNH4OHresulted
in a bidimensional hexagonal close-packed (HCP) structure with a lattice
parameter of 70 Å. In the WG films with NH4OH, a highly polymerized
protein pattern with intimately mixed glutenins and gliadins bounded
through SH/SS interchange reactions was found. A large content of β-
sheet structures was also found in these... (More) - Evaluation of structure and morphology of extruded wheat

complexities of the supramolecular structures and conformations of wheat
gluten polymeric proteins in biofilms not previously reported for biobased
materials. (Less)
