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.
