Discussing the state-of-the-art of the proposed topics in one single book for probing the polar metabolome, using relevant examples, is unique and needed in the metabolomics field.

The efficient analysis of polar and charged metabolites in biological samples remains a huge challenge in the field of metabolomics. Over the past years, novel mass spectrometry-based analytical tools have been developed to enable the sensitive and efficient profiling of polar ionogenic metabolites in various biological samples. This book gives the reader a comprehensive overview of these recent technological developments. Topics covered include the use of chemical labelling strategies for allowing the analysis of polar metabolites using reversed-phase liquid chromatography–mass spectrometry (RPLC-MS) and the latest methodological developments in RPLC-MS, hydrophilic interaction liquid chromatography (HILIC)-MS and ion-pair LC-MS approaches. Attention is also paid to developments in nano-LC-MS and capillary electrophoresis–mass spectrometry methods specifically for profiling polar metabolites in small volume biological samples. The utility of ion-mobility MS and NMR spectroscopy will also be outlined. Sample preparation is the key part in the analytical workflow employed for metabolomics. Therefore, ample emphasis will be given on recent solid-phase extraction and solid-phase micro-extraction methods. Finally, analytical techniques for chiral metabolic profiling will also be considered. Discussing the state-of-the-art of the proposed topics in one single book for probing the polar metabolome, using relevant examples, is unique and needed in the metabolomics field. This book has relevance and appeal to an international audience of analytical and biomedical researchers in industry and academia.

Metabolomics is increasingly being used to explore the dynamic responses of living systems in biochemical research. The complexity of the metabolome is outstanding, requiring the use of complementary analytical platforms and methods for its quantitative or qualitative profiling. In alignment with the selected analytical approach and the study aim, sample collection and preparation are critical steps that must be carefully selected and optimized to generate high-quality metabolomic data. This book showcases some of the most recent developments in the field of sample preparation for metabolomics studies. Novel technologies presented include electromembrane extraction of polar metabolites from plasma samples and guidelines for the preparation of biospecimens for the analysis with high-resolution μ magic-angle spinning nuclear magnetic resonance (HR-μMAS NMR). In the following chapters, the spotlight is on sample preparation approaches that have been optimized for diverse bioanalytical applications, including the analysis of cell lines, bacteria, single spheroids, extracellular vesicles, human milk, plant natural products and forest trees.
