The casting method to form dimyristoyl phosphatidyl choline (DMPC) mimetic biomembrane on an Au electrode is proposedThe results of ellipsometer and electrochemical methods confirmed that the film is a compact membrane that can block the electron transferring processp-Dihydroxybenzene can reach the electrode surface and occur redox reactions by passing through transient defects in individual bilayersSuch defects occur in biomembranes and are accentuated by relatively small electric fieldsThe electrochemical behavior of p-dihydroxybenzene in this membrane was also investigated p-Dihydroxybenzene is biologically important molecule because of its function of transferring electrons in lipid layersThis reaction occur in the bionic environment

which provide the useful help to study the real reaction of small molecules in the biological organismsStudies on the electrochemical behavior of p-dihydroxybenzene in the DMPC biomimetic membrane provide useful information for elucidating biological electron transfer processes concerning lipid layers
