单不饱和脂质和多不饱和脂质广泛分布于自然界中,并且在结构和功能上是具有多种物理化学、生物学、医学和营养特性的不同类别的分子。高分辨率NMR光谱技术,包括1H-,13 C-和31 P-NMR已成功地用作不饱和脂质的结构和分析工具。这篇综述文章的目的是提供:(i)关键的1H-,13 C-和31 P-NMR参数的结构和分析研究的概述;(ii)已用于共振分配的各种一维和二维NMR技术的概述;(三)选定的分析和结构研究,重点是鉴定复合脂质提取物中的主要和次要不饱和脂肪酸而不需要单独的成分的隔离;(iv)脂质的氧化产物的选择调查;(v)在脂质组学的新兴领域的应用;(vi)在分子水平上的蛋白质-脂质相互作用的研究;(vii)实际考虑和(viii)在该领域的未来发展的概述。
Mono- and polyunsaturated lipids are widely distributed in Nature, and are structurally and functionally a diverse class of molecules with a variety of physicochemical, biological, medicinal and nutritional properties. High resolution NMR spectroscopic techniques including 1H-, 13C- and 31P-NMR have been successfully employed as a structural and analytical tool for unsaturated lipids. The objective of this review article is to provide: (i) an overview of the critical 1H-, 13C- and 31P-NMR parameters for structural and analytical investigations; (ii) an overview of various 1D and 2D NMR techniques that have been used for resonance assignments; (iii) selected analytical and structural studies with emphasis in the identification of major and minor unsaturated fatty acids in complex lipid extracts without the need for the isolation of the individual components; (iv) selected investigations of oxidation products of lipids; (v) applications in the emerging field of lipidomics; (vi) studies of protein-lipid interactions at a molecular level; (vii) practical considerations and (viii) an overview of future developments in the field.
