Abstract
The major protein fraction, alpha-globulin, of sesame seed CS’esamum indicum L.) contains subunits
which are associated predominantly by hydrophobic interactions. Effects of various salts show the
following effectiveness of anions in dissociating the proteins, SO,*- < Cl- < Br- < C104- < SCN- 4
I- < CCl,COO-, the first two members being association-inducing ions. CC1,COONa is found to be
the most effective among the series in causing dissociation. The cations Lit, Na+, K+, and Cs+ induce
association, the order of effectiveness being Cs+ - K+ > Na+ > IA+. The low concentration of salts
(anions) necessary to induce dissociation does not involve a detectable change in protein conforma-
tion. The discrepancy between the effectiveness of the anions in dissociating the protein and the
Hofmeister pattern of these ions has been discussed.
