对菠菜叶绿体包膜中主要的中性脂、糖脂和磷脂进行了脂肪酸的比例、位置分布和配对分析。从先前的全叶脂质分析中已知的脂质中二酰基甘油部分的所有特异性也在包膜脂质中发现。二酰基甘油和半乳糖脂具有共同的二酰基甘油部分。唯一的例外是双半乳糖二酰基甘油，它含有18:3/16:0，但缺乏18:3/16:3，与其他半乳糖脂的分布相反。磷脂酰胆碱、磷脂酰甘油和磺基喹啉二酰基甘油与半乳糖脂不同，因为每一种都有独特的二酰基甘油谱。磷脂酰胆碱和半乳糖脂中存在的二酰基甘油种类或游离二酰基甘油在包膜水平上不能为磷脂酰胆碱和半乳糖脂之间的生物遗传学关系提供证据。
The major neutral, glycolipids and phospholipids from envelopes of spinach chloroplasts were analyzed with respect to proportions, positional distribution and pairing of fatty acids. All specificities in the diacylglycerol portions of lipids known from previous analyses of lipids from whole leaves were also found in envelope lipids. Diacylglycerols and galactolipids share a common diacylglycerol portion. The only exception is digalactosyl diacylglycerol, which contains 18:3/16:0 but lacks 18:3/16:3 species reverting the distribution in other galactolipids. Phosphatidylcholine, phosphatidylglycerol and sulfoquinovosyl diacylglycerol are distinct from the galactolipids, because each one has a unique diacylglycerol profile. The diacylglycerol species present in phosphatidylcholine and galactolipids or free diacylglycerols do not provide evidence for a biogenetic relation between phosphatidylcholine and galactolipids at the level of envelopes.
