Three partial benzyl esters of gellan have been studied by means of circular dichroism spectroscopy in aqueous tetramethylammonium chloride solution and in the gel state (aqueous NaCl). Thermal stability of the solution ordered chain states as well as of the gels, maximal in the case of gellan, markedly decreases with increasing degree of esterification.
