The molecular weight of electrophoretically pure gamma-gliadin from Ponca flour was determined in an ultracentrifuge by the sedimentation equilibrium method. In 6M guanidine hydrochloride plus 0.1M acetic acid (pH 3.3), both weight average and Z-average molecular weight are 31,000. In aluminum lactate-lactic acid (micron = 0.1, pH 3.1), gamma-gliadin is aggregated. Its apparent weight average is 33,000 and Z- average molecular weight, 42,000.
