Metabolomics:

Together, genomics, proteomics and transcriptomics are powerful approaches to increasing our understanding not only of how cells function normally but also what the key modifications are in disease and so will find increasing use in the diagnosis of specific diseases and in the identification and assessment of new chemotherapeutic agents. The Metabolomics is perhaps the newest of these fields of study and relates to the study of the little molecule parts of the cell, which is, the metabolome. Through analyzing the metabolites of a cell, one can produce a metabolic profile which indicates the cell's metabolic activity; information that should prove useful for a range of applications, involving clinical diagnostics and drug discovery. The methods of metabolomics center on techniques to divide the several classes of small molecules, like as gas liquid chromatography, elevated performance liquid chromatography and capillary electrophoresis, followed through identification using, for instance, mass spectrometry. So far, methods for large-scale metabolomic analyses along the lines of those employed for proteomics, genomics and transcriptomics have still to be established.
