Diversity of the Soybean Protein-phosphatidylcholine Complex

Abstract

Phosphatidylcholine was associated with defatted soybean protein to produce multiform complexes by sonication. The lipid was non-specifically bound to either 7 S and 11 S proteins. As the ultrasonic power increased, the protein-phosphatidylcholine complexes to be sedimented to the bottom by sucrose density gradient centrifugation increased. Oil was associated with the protein-phosphatidylcholine complexes to form the ternary complexes.
