脂质种类具有非常不同的结构,导致它们在生物系统中非常多样化的细胞功能。脂质组学代表了一种强大的技术,用于深入分析数百至数千种完整的脂质分子种类。在目前的研究中,当我们在正离子模式下使用基于多维质谱的鸟枪脂质组学策略通过162 Da的中性丢失扫描对大鼠脊髓样品中的β-D-糖苷类进行分析时,显示了一簇未知的离子峰。为了鉴别这些未知离子峰的结构特性,通过高质量分辨率质谱法对这些离子进行了MS 2和MS 3分析。大量的证据使我们能够确定这些未知的离子峰是单己糖基烷基-酰基甘油(HAAG)物质,包括它们的sn-位置异构体和烷基-酰基组成异构体。我们还应用所开发的方法来鉴定和定量存在于各种小鼠神经组织中的HAAG种类。我们相信,对哺乳动物神经组织样本中存在的HAAG物种的第一种脂质组学研究为这一未知领域的未来生物学研究提供了基础。
Lipid species possess very different structures, leading to their very diversified cellular functions in biological systems. Lipidomics represents a powerful technology for deep analysis of hundreds to thousands of intact lipid molecular species. In the current study, a cluster of unknown ion peaks was displayed when we profiled cerebroside species in rat spinal cord samples by neutral loss scan of 162 Da in the positive ion mode using a multi-dimensional mass spectrometry-based shotgun lipidomics strategy. In order to identify the structural identities of these unknown ion peaks, MS2 and MS3 analyses of these ions were performed by high mass resolution mass spectrometry. Extensive lines of evidence allowed us to identify that these unknown ion peaks were monohexosyl alkyl-acyl glycerol (HAAG) species, including their sn-positional isomers and alkyl-acyl compositional isomers. We also applied the developed method to identify and quantify HAAG species present in a variety of mouse nerve tissues. We believe that the first kind of lipidomics study on HAAG species present in mammalian nerve tissue samples provided the foundation for future biological research in this unknown area.
