Cells of Thermoplasma acidophilum contain about 3% total lipid on a dry weight basis. Total lipid was found to contain 17.5% neutral lipid, 25.1% glycolipid, and 56.6% phospholipid by chromatography on silicic acid. The lipids contain almost no fatty acid ester groups but appear to have long-chain alkyl groups in ether linkages to glycerol. The phospholipid fraction includes a major component which represents about 80% of the lipid phosphorus and 46% of the total lipids. We believe this component to be a long-chain isopranol glycerol diether analogue of glycerolphosphoryl monoglycosyl diglyceride. The glycolipids appear to contain isopranol diether analogues. Several components of the complex, neutral lipid fraction have been identified as hydrocarbons, vitamin K(2)-7, and isopranol glycerol diether analogues. Sterols are present in the neutral lipids but do not appear to be synthesized by the organism.
嗜酸热原体的细胞在干重基础上含有约3%的总脂质。通过硅酸柱色谱法发现，总脂质中含有17.5%的中性脂质、25.1%的糖脂和56.6%的磷脂。这些脂质几乎不含脂肪酸酯基团，但似乎含有通过醚键与甘油相连的长链烷基。磷脂部分包括一种主要成分，约占脂质磷的80%和总脂质的46%。我们认为该成分是甘油磷酸单糖基二甘油酯的长链异戊醇甘油二醚类似物。糖脂似乎含有异戊醇二醚类似物。复合中性脂质部分的几个成分已被鉴定为烃类、维生素K(2)-7和异戊醇甘油二醚类似物。中性脂质中存在甾醇，但似乎不是由该生物体合成的。
