A collection of literature and in-house MSn spectra data for research on plant metabolomics.

A web-based resource for identification of compounds of interest based on chemical properties of a molecule, such as accurate mass and fragment ion spectral pattern generated by mass spectrometry (MS)

It contains high-resolution, accurate mass MS/MS spectra of over 13,000 metabolic compounds for the seamless identification of metabolites.

Interface to visualize genome-scale data on biochemical pathway maps

A freely searchable collection of spectra, spectral trees, structures, fragments, precursor ions, chromatographic data and compound related references

An international repository for metabolomics data and metadata, metabolite standards, protocols, tutorials and training, and analysis tools

A database for Metabolomics experiments and derived information.

The EcoCyc project performs literature-based curation of its genome, and of transcriptional regulation, transporters, and metabolic pathways.

Can be used to quantify and identify metabolites, lipids and proteins in samples

MetaCyc contains pathways involved in both primary and secondary metabolism, as well as associated metabolites, reactions, enzymes, and genes.

HumanCyc provides an encyclopedic reference on human metabolic pathways, the human genome, and human metabolites.

Human metabolic pathways, reactions, proteins, links to other databases
