  Improved LC−MS Method for the Determination of Fatty Acids in Red Blood Cells by LC−Orbitrap MS

  摘要：

  我们报告了一种通过液相色谱质谱联用（LC−MS）快速且灵敏分析红细胞（RBC）中生物学相关的脂肪酸（FAs）的新方法。该方法开发了一种形成吡啶甲酰胺的新化学衍生化途径，通过定量反应从FAs中生成。包括从C14到C22的饱和及不饱和FAs在内的14种衍生化FA标准品，在15分钟内得以高效分离。此外，采用最近推出的台式轨道阱质谱仪在正离子电喷雾电离（ESI）全扫描模式下进行检测，相较于传统串联MS方法，灵敏度提高了2至10倍，对饱和及不饱和FAs的检测限达到了低飞摩尔水平。所开发的方法被应用于测定RBC中的FA浓度，其日内和日间变异系数均低于10%。

  AbstractLow‐energy collision‐induced dissociation of some representative 3‐picolinyl esters of fatty acids were investigated. The daughter‐ion spectra of the precursor ions showed similar features to the electron impact mass spectra, but the low intensity of the parent‐ion signal did not allow reliable deductions. The parent‐ion spectra of some fragments that retain the pyridine derivatizing group contain structurally useful information, and are suitable for analytical application. These spectra also contain fragment ions which may account for an alternative pathway to that currently proposed for the generation of certain fragment ions within the ion source. Both pathways were investigated in this tandem mass spectrometric study. Isomerization and decomposition of distonic fragment ions through loss of alkenes yield species with a shorter alkyl chain, which are particularly stable when they contain allylic radicals.

  We report a new method for fast and sensitive analyses of biologically relevant fatty acids (FAs) in red blood cells (RBC) by liquid chromatography mass spectrometry (LC−MS). A new chemical derivatization approach was developed forming picolylamides from FAs in a quantitative reaction. Fourteen derivatized FA standards, including saturated and unsaturated FAs from C14 to C22, were efficiently separated within 15 min. In addition, the use of a recently introduced benchtop orbitrap mass spectrometer under positive electrospray ionization (ESI) full scan mode showed a 2−10-fold improvement in sensitivity compared with a conventional tandem MS method, with a limit of detection in the low femtomole range for saturated and unsaturated FAs. The developed method was applied to determine FA concentrations in RBC with intra- and interday coefficients of variation below 10%.
