Urea-Elicited Changes in Relative Electrophoretic Mobility of Certain Glycinin and β-Conglycinin Subunits

Abstract
Six molar urea in sodium dodecyl sulfate-polyacrylamide gels altered the relative electrophoretic mobility of several soybean protein subunits. Glycinin acidic polypeptide components A3 and A4 could be resolved from the other acidic polypeptides. A variant of the δ′ subunit of β-conglycinin was identified.
