Metabolomics are a newly emerging field of Systems Biology research and are focused on the high-throughput identification, characterization and quantification of small molecules (<1500 Da) which compose the metabolome, the final products of cell metabolism(1) . The science was founded in the1970s to 1980s(2) with early studies on urinary metabolites by gas chromatography-mass spectrometry (GC-MS), but the term metabolomics appeared in the scientific literature for the first time in 1998(3) , in the study on the yeast genome,Saccharomyces Cerevisiae by Oliver et al. Since then, 6446 metabolomic studies have been published including 1253 reviews and 741 articles have appeared in the first 6 months of this year confirming the great interest shown for research in this field.
