Since may 2015 the PeakForest database is gathering Chemical Libraries and Spectra from each MetaboHUB partners.

  • Number of Chemical Compound:
  • Number of Reference Chemical Compound:
  • Number of NMR spectra:
  • Number of LC-MS spectra:
  • Number of LC-MSMS spectra:
  • Percentage of Ref. Chemical Compound with at least one spectrum: %
For Biological informations: please refer to MetExplore statistics.

This table shows how PeakForest chemical library covers genome scale reconstructions of metabolic networks. This mapping is performed using MetExplore webservice. MetExplore stores metabolic networks coming from various sources (SBML files, KEGG, BioCyc).
If you want to perform mapping of your data in networks, please visit

This table is automatically generated once a week in order to keep up to date with latest changes in both PeakForest and MetExplore.

Note: number of metabolites in each network is not covering the entire of each metabolome. Indeed some parts like lipids are defined by compound families (e.g. a sphingolipid). Moreover, since these reconstructions are based on genome they may miss some reactions".

Some PeakForest's database functionalities will be available through Galaxy tools and workflows.
PeakForest in Galaxy
Please refer to W4M project for further informations.

In order to share metabolomics analysis strategies and centralize tools and practices, the web-based platform Galaxy is the core component of the W4M infrastructure. Galaxy provides several interesting features for metabolomics tools integration compared to other workflow engines. This cross-platform system enables scientist without programming experience to design and run analysis workflows.

This chart shows a representation of the PeakForest chemical library content repartition in two major biofluids (Human blood or urine). This biological distribution is based on the use of the solubility property of each metabolite.
The logP values are computed thanks to Open Babel software [J. Cheminf. 2011, 3:33].
