摘要：

A localized lateral proton pathway is present along the phospholipid polar heads and bound water molecules when the lipids are spread in monolayers at the air/water interface. Conduction can be detected on concentrated buffers as found under physiological conditions if the lateral proton gradient is large enough. The localized movement supports the occurrence of microlocalized proton circuits along a membrane and of lateral proton gradients.
