Are the carboxyl groups of pectin polymers the only metal-binding sites in plant cell walls? To answer this question we investigated Cu2+ and Ni2+ -exchange capacities of isolated root cell walls of seven plant species. As the ionization degree of carboxyl groups and consequently their ability to bind metal ions is dependent upon the solution pH it is(More)
Ion-exchange capacity of the cell walls isolated from suspension-cultured Panax japonicus, Polyscias filicifolia and Dioscorea deltoidea cells was analyzed at pH 2.8–12 and constant ionic strength (100 mM). The cell walls of all cultures contain three types of ion-exchange groups: primary amino groups (pK a < 3), carboxyl groups of polygalacturonic acid (pK(More)
