The volume brings together some of the best experts in the field of modern metabolomics to discuss various techniques used today to study specific metabolite classes, and metabolomics in bacterial systems and mammalian systems. The chapters in this book cover topics such as Isotopic Ratio Outlier Analysis (IROA) for quantitative analysis; cholesterol and derivatives in ocular tissues using LC-MS/MS methods; microbial siderophores analysis by mass spectrometry; the metabolomic study of tissues in Parkinson's Disease; and NMR analysis in livestock metabolomics. Written in the highly successful Methods in Molecular Biology series format, the chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step readily reproducible laboratory protocols, tips on troubleshooting and avoiding pitfalls. Cutting-edge and thorough, Metabolomics: Methods and Protocols is an essential resource for any researcher interestedin this exciting and evolving field.
