Molecular motion of dipalmitoylphosphatidylcholine (DPPC)/CaCI 2 lamellae in a gel phase was studied by pulse NMR. Proton 1/T a for DPPC in a gel phase showed that the rate of reorientation about the long axis of the lipid molecule decreased gradually from 0 to 500 mM CaCl 2. At 10--50 mM CaCl 2 the
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
