Calorimetric and freeze-etch study of the influence of Mg2+ on the thermotropic behaviour of phosphatidylglycerol

P H Ververgaert et al. Chem Phys Lipids. 1975 Feb.

Abstract

In the presence of Mg2+ 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 Ca2+ ions (Biochim. Biophys. Acta 39. (1974)432)9 It is demonstrated that the heat content of this phospholipid is dependent on the ionic environment.
