Abstract

alpha-globulin, the major fraction of sesame seed (Sesamum indicum L.) proteins, coagulates on heating. Dissociation, denaturation, and aggregation of the protein upon heating were studied by gel filtration, polyacrylamide gel electrophoresis, sedimentation velocity, pktapp of tyrosyl groups, and fluorescence measurements. Addition of beta-mercaptoethanol does not reduce the extent of heat coagulation. The reassociation of heat denatured subunits through hydrophobic interaction results in the formation of insoluble precipitate.
