Glucose-substituted cardiolipins account for about 4 mol% of total phospholipid extracted from exponentially grown cells of Geobacillus stearothermophilus NRS 2004/3a. Individual glucocardiolipin species exhibited differences in fatty acid substitution, with iso-C(15:0) and anteiso-C(17:0) prevailing. The compounds were purified to homogeneity by a novel protocol and precharacterized by matrix-assisted laser desorption ionization time-of-flight mass spectrometry.
葡萄糖取代的心磷脂约占从嗜热栖热放线菌NRS 2004/3a指数生长期细胞中提取的总磷脂的4摩尔%。各个葡萄糖心磷脂种类在脂肪酸取代方面存在差异,其中异-C(15:0)和anteiso-C(17:0)占主导。通过一种新方法将这些化合物纯化至同质,并通过基质辅助激光解吸电离飞行时间质谱进行预表征。
