Resumen:
Modifications in the hydration of the phosphates groups of different PE´s in comparison to PC´s with similar chain length were studied by FTIR. The shift in the band of the antisymmetric stretching of the phosphates was correlated with the changes in the dipole potential, surface charges and area per lipid. Cyclic voltammetry experiments at mercury-phospholipids-water interfaces were performed to analyze lateral head group and hydration interactions.
