通过高分辨率 C-13-、P-31 和 H-1-NMR 测定了来自 Acholeplasmalaidlnwii 菌株 A-EF22 膜的两种磷酸糖脂的结构。有问题的脂质是 1,2-二酰基-3-O-[甘油磷酰基-6-O-(α-D-吡喃葡萄糖基- (1 --> 2)-O-α-D-吡喃葡萄糖基)]-sn-甘油 (1) 和 1,2-二酰基-3-O-[甘油磷酰基-6-O-(α-D-吡喃葡萄糖基-(1 -->) 2)-单酰基甘油磷酰基-6-O-α-D-吡喃葡萄糖基)]-sn-甘油(2)。因此，两种脂质都是二葡萄糖基二酰基甘油的衍生物。之前关于这些脂质的报告基于不充分的化学分析，显示出相互矛盾的结构。先前没有描述过具有2的结构的磷酸糖脂。
The structures of two phosphoglucolipids from the membrane of Acholeplasma laidlnwii, strain A-EF22 were determined by high resolution C-13-, P-31 and H-1-NMR. The lipids in question are 1,2-diacyl-3-O-[glycerophosphoryl-6-O-(alpha-D-glucopyranosyl- (1 --> 2)-O-alpha-D-gloucopyranosyl)]-sn-glycerol (1) and 1,2-diacyl-3-O-[glycerophosphoryl-6-O-(alpha-D-glucopyranosyl-(1 --> 2)-monoacylglycerophosphoryl-6-O-alpha-D-glucopyranosyl)]-sn-glycerol (2). Both lipids are thus derivatives of diglucosyldiacylglycerol. Previous reports on these lipids, based on insufficient chemical analyses, showed contradictory structures. A phosphoglycolipid having the structure of 2 has not been described previously.
