Abstract
The structures formed by aqueous dispersions of cardiolipin isolated from bovine heart and B. subtilis have been studied by 31P-NMR and freeze-fracture electron microscopy. The sodium salts of both cardiolipins form bilayers. The Ca2+, Mg2+ and Ba2+ salts undergo well-defined bilayer leads to hexagonal (HII) transitions, the temperature of which is dependent on the cation involved and the fatty acid composition of the cardiolipin.
摘要
通过31P-NMR和冷冻断裂电子显微镜研究了从牛心和枯草芽孢杆菌中分离出的心磷脂水分散体形成的结构。两种心磷脂的钠盐均形成双层结构。Ca2+、Mg2+和Ba2+盐会发生明确的双层向六方（HII）相的转变，转变温度取决于所涉及的阳离子和心磷脂的脂肪酸组成。
