Two novel glycolipids with a very rare alpha(1-->4) diglucosyl structure have been isolated from the thermophilic bacterium Thermotoga maritima. The structures of these compounds, on the basis of chemical procedures and spectroscopic studies (FAB-MS and NMR), were shown to be: 1(3),2-dipalmitoyl-3(1)-[glucopyranosyl-(6-decanoyl)-alpha-D-(1-->4)- glucopyranosyl-alpha-D]-glycerol (Glycolipid 1) and 1(3),2-dipalmitoyl-3(1)-[glucopyranosyl-alpha-D-(1-->4)-glucopyranosyl- alpha-D]-glycerol (Glycolipid 2).
从嗜热细菌海栖热袍菌中分离出了两种具有非常罕见的α(1→4)二葡糖基结构的新型糖脂。基于化学方法和光谱研究(快原子轰击质谱法和核磁共振),这些化合物的结构显示为:1(3),2 - 二棕榈酰 - 3(1)-[吡喃葡萄糖基-(6 - 癸酰基)-α - D-(1→4)-吡喃葡萄糖基-α - D]-甘油(糖脂1)和1(3),2 - 二棕榈酰 - 3(1)-[吡喃葡萄糖基-α - D-(1→4)-吡喃葡萄糖基-α - D]-甘油(糖脂2)。
