The amount of pectin held in cell walls by ionic bonds only was determined by extraction with cyclohexanediamine tetraacetic acid (CDTA) at room temperature, to remove calcium ions without degrading the galacturonan chains. Enzymic degradation was avoided by extracting the cell walls with phenol-ace
By the use of calcium and sodium specific electrodes, the study of the ionic interactions with well-characterized pectins has shown a greater affinity of pectins towards calcium ions when the degree of methylation of the samples and the ionic strength of the systems decreased. The affinity of pectic
