贝壳是一种无细胞生物矿物质，其中的大分子结构与矿物相密切相关。尽管已经描述了糖，但大多数研究都致力于蛋白质。从两种软体贝壳的方解石柱状层和文石珍珠层中提取脂类。傅里叶变换红外光谱分析表明，两个样品中都存在脂类，但它们并不相似。薄层层析证实了两个被研究层中的脂类是不同的，因此可以认为它们是物种依赖的。尽管尚未破译，但它们在生物矿化和化石过程中的作用可能很重要。(C)2008 Elsevier Inc.保留所有权利。
Mollusc shells are acellular biominerals, in which macromolecular structures are intimately associated with mineral phases. Most studies are devoted to proteins, despite sugars have been described. Lipids were extracted from the calcite prismatic and aragonite nacreous layer of two mollusc shells. Fourier Transform Infrared Spectrometry shows that lipids are present in both samples, but they are not similar. Thin layer chromatography confirms that lipids are different in the two studied layers, so that it may be suggested they are species-dependant. Although not yet deciphered, their role in biomineralization and fossilisation processes is probably important. (c) 2008 Elsevier Inc. All rights reserved.
