如大量研究的二肉豆蔻酰PC（DMPC）双层，单甲基和二甲基二肉豆蔻酰磷脂酰乙醇胺（DMPE）脂质双层的对齐堆叠随着流体相中的温度朝向主转变温度T（M）降低而以临界方式剧烈膨胀。与DMPC双层不同，在低于T（M）时，单甲基和二甲基DMPE都经历到凝胶相而不是波纹相的转变。虽然它是不完全理解为什么有异常溶胀，我们目前的结果应有助于理论表明，低于T（M）的相的形成是不相关的临界现象以上T（M）。
Aligned stacks of monomethyl and dimethyl dimyristoyl phosphatidylethanolamine (DMPE) lipid bilayers, like the much studied dimyristoyl PC (DMPC) bilayers, swell anomalously in a critical fashion as the temperature is decreased within the fluid phase towards the main transition temperature, T(M). Unlike DMPC bilayers, both monomethyl and dimethyl DMPE undergo transitions into a gel phase rather than a rippled phase below T(M). Although it is not fully understood why there is anomalous swelling, our present results should facilitate theory by showing that the formation of the phase below T(M) is not related to critical phenomena above T(M).
