The behaviour of the high molecular-weight glutenin subunit 1Dx5, the 58 kDa central repetitive domain and a-gliadins at the air-aqueous interface.
(2003) In Journal of Cereal Science 38(2). p.147-156- Abstract
- The surface pressure–molecular area (–A) relationship for spread layers of the high molecular-weight glutenin subunit 1Dx5, a 58 kDa peptide derived from the central repetitive domain of the subunit, and an -gliadin fraction was measured by means of a surface film balance (Langmuir trough). The aqueous phase was a 10 mM acetate buffer, pH 4.0, either with or without 100 mM NaCl. Subunit 1Dx5 generated much higher surface pressures than the 58 kDa peptide, whereas the -gliadin fraction generally gave higher surface pressures than subunit 1Dx5. Furthermore, subunit 1Dx5, but not the 58 kDa peptide or the -gliadin fraction, formed a highly cohesive film. The differences in the interfacial behaviour of subunit 1Dx5 and the 58 kDa peptide were... (More)

Furthermore, subunit 1Dx5, but not the 58 kDa peptide or the -gliadin fraction, formed a highly cohesive film. The differences in the interfacial behaviour of subunit 1Dx5 and the 58 kDa peptide were ascribed to significant hydrophobic interactions for the subunit. The reversibility of a compression–expansion cycle was generally greater for the second cycle than for the first. For subunit 1Dx5 and the -gliadins, but not the 58 kDa peptide, the reversibility was increased when NaCl was present in the aqueous phase. (Less)
