Metabolites are small molecules produced by enzymatic reactions in a given
organism. Metabolomics or metabolic phenotyping is a well-established omics aimed
at comprehensively assessing metabolites in biological systems. These
comprehensive analyses use analytical platforms, mainly nuclear magnetic
resonance spectroscopy and mass spectrometry, along with associated separation
methods to gather qualitative and quantitative data. Metabolomics holistically
evaluates biological systems in an unbiased, data-driven approach that may
ultimately support generation of hypotheses. The approach inherently allows the
molecular characterization of a biological sample with regard to both internal
(genetics) and environmental (exosome, microbiome) influences. Metabolomics
workflows are based on whether the investigator knows a priori what kind of
metabolites to assess. Thus, a targeted metabolomics approach is defined as a
quantitative analysis (absolute concentrations are determined) or a
semiquantitative analysis (relative intensities are determined) of a set of
metabolites that are possibly linked to common chemical classes or a selected
metabolic pathway. An untargeted metabolomics approach is a semiquantitative
analysis of the largest possible number of metabolites contained in a biological
sample. This is part I of a review intending to give an overview of the state of
the art of major metabolic phenotyping technologies. Furthermore, their inherent
analytical advantages and limits regarding experimental design, sample handling,
standardization and workflow challenges are discussed.
