RESUMO

Soybean (Glycine max) storage proteins were characterized by sedimentation and by polyacrylamide gel electrophoresis under dissociating (8 m urea) and nondissociating conditions. Three sedimenting classes of proteins were found, with sedimentation coefficients of 2.2S, 7.5S, and 11.8S. The coefficients were related to the bands obtained by electrophoretic separation. The results support the idea that relatively few proteins make up the bulk of the seed protein.
