We have identified phosphatidylethanolamine as one of the major phospholipids of Clostridium perfringens by two dimensional thin layer chromatography of the intact lipids and of their deacylation products and by liquid chromatography followed by mass spectrometry of the intact neutral phospholipid fraction. The principal fatty acids of phosphatidylethanolamine are myristic acid (14:0), lauric acid (12:0), and palmitic acid (16:0) and the major molecular species are 14:0,14:0 (26.3%); 12:0,14:0 (19.0%); 14:0,16:0 (22.4%) and 16:0,16:0 (17.6%). A similar distribution of molecular species was found in the other major phospholipid, O-alanyl phosphatidylglycerol.
通过对完整脂质及其脱酰基产物进行二维薄层色谱分析,以及对完整中性磷脂部分进行液相色谱-质谱联用分析,我们已确定磷脂酰乙醇胺是产气荚膜梭菌的主要磷脂之一。磷脂酰乙醇胺的主要脂肪酸为肉豆蔻酸(14:0)、月桂酸(12:0)和棕榈酸(16:0),主要分子种类为14:0,14:0(26.3%);12:0,14:0(19.0%);14:0,16:0(22.4%)和16:0,16:0(17.6%)。在另一种主要磷脂O-丙氨酰磷脂酰甘油中也发现了类似的分子种类分布。
