Gliadins from undefatted and completely defatted flour were fractionated by gel filtration chromatography on a Sephadex G-200 column. Fraction I (excluded) from undefatted flour contained almost all of the sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) subunits of the original unfractionated gliadin. After removal of lipids from this fraction, its protein was resolved into five peaks (fractions) on rechromatography on Sephadex G-200. The five protein fractions of the gliadin from defatted flour were reconstituted with the original lipids and chromatographed on Sephadex G-200. SDS-PAGE showed that the subunit composition of fraction I was similar to that of the original gliadin from undefatted flour. It was concluded that the lipid-mediated aggregation of high and low molecular weight subunits of gliadin is reversible.
