Joint influence of the pH and the ionic strength of a solution on the degree of association of N-(monohydroxyfullerenyl)-DL-alanyl-DL-alanine in aqueous solution

Abstract

It has been found that the degree of association of the alanylalanine derivative of fullerene in neutral and alkaline media at an ionic strength of 0.1 is virtually independent of the pH of the solution but is a function of only its ionic strength, whereas in acidic media, the pH of the solution has a crucial influence on the degree of association of this fullerene derivative.
