EFFECT OF SUCCINYLATION ON THE OLIGOMERIC STRUCTURE OF ARACHIN*

Abstract
Arachin [Arachis hypogaea] succinylated to various levels was studied by the techniques of sedimentation velocity, viscosity, absorption and fluorescence spectra, optical rotation and circular dichroism. Succinylation up to 60% leads to the dissociation of the parent 14S molecule to 9S and 4S fractions; above 60% succinylation, 4S fraction occurs predominantly. The other measured properties also show a gradual change up to 50% succinylation and a marked change above this level. The observed changes suggest that a new organized structure is formed before the 4S fraction is denatured.
