Acyl phosphatidylglycerol, isolated from Escherichia coli, has been identified as 3-sn-phosphatidyl-1'-(3'-acyl)-sn-glycerol. The fatty acids of the diacylglycerol moiety of acyl phosphatidylglycerol resemble those of phosphatidylglycerol in composition. However, the monoacylglycerol moiety of this lipid contains more unsaturated fatty acids than the diacylglycerol part of this lipid or other phospholipids in E. coli. Furthermore, the fatty acids present in the monoacylglycerol moiety, were found to contain major amounts of an unsaturated acid identified as 7-tetradecenoic acid by combined gas-liquid chromatography-mass spectrometry. This acid was present only in low concentrations in most phospholipids of E. coli.
从大肠杆菌中分离出的酰基磷脂酰甘油已被鉴定为3-sn-磷脂酰-1'-(3'-酰基)-sn-甘油。酰基磷脂酰甘油的二酰基甘油部分的脂肪酸在组成上与磷脂酰甘油的相似。然而，这种脂质的单酰基甘油部分比该脂质的二酰基甘油部分或大肠杆菌中的其他磷脂含有更多的不饱和脂肪酸。此外，通过气相色谱-质谱联用分析发现，单酰基甘油部分存在的脂肪酸中含有大量被鉴定为7-十四碳烯酸的不饱和酸。这种酸在大肠杆菌的大多数磷脂中仅以低浓度存在。
