In the presence of Mg 2+ ions phosphatidylglycerol shows supercooling which leads to the formation of a metastable gel phase. This contrasts with the behaviour of this negatively charged phospholipid in the presence of Ca 2+ ions (Biochim. Biophys. Acta 339 (1974) 432). It is demonstrated that the h

A theory is presented on the electrostatic properties of the surface area of phosphatidylglycerol monolayers spreading at an air-water interface in the presence of monovalent and divalent cations. In the present theory, the adsorption of monovalent and divalent cations to the membranes is taken into
