The transformation between inverse bicontinuous cubic phases of a lipid from diamond (QII(D)) to gyroid (QII(G)) in the single crystal region of monoolein was studied. X-ray diffraction data indicate that the single orientation of the QII(D) phase was converted into an almost single orientation of the QII(G) phase. The [111] and [11̅0] directions of a single crystal of the QII(D) phase corresponded to the [202] and [04̅0] directions of the QII(G) phase, respectively. This orientation relationship indicated that one direction in the four-branched water channels of the QII(D) phase was preserved in the three-branched water channels of the QII(G) phase. Using this relationship, a transformation model was constructed in which one direction of the water channels was preserved while another direction appeared.
研究了单油酸甘油酯单晶区域中脂质从菱形（QII(D)）到螺旋状（QII(G)）的反双连续立方相之间的转变。X射线衍射数据表明，QII(D)相的单一取向转变为QII(G)相几乎单一的取向。QII(D)相单晶的[111]和[11̅0]方向分别对应于QII(G)相的[202]和[04̅0]方向。这种取向关系表明，QII(D)相四分支水通道中的一个方向在QII(G)相的三分支水通道中得以保留。利用这种关系，构建了一个转变模型，其中水通道的一个方向得以保留，而另一个方向出现。
