Welcome to PathCase Family of Applications

Each PathCase application below contains a different set of tools. All applications store, query, and visualize metabolic pathways, in addition to their specialized tasks. For more information on each PathCase application, please check out the links located below.




Current Research


This system, currently being developed by a grant from NSF Biology, integrates metabolic pathways with systems biology models. The aim of the PathCaseSB project is to build a framework and tools towards effective and efficient systems biology model development for multiscale mechanistic models of biological systems.

Data Sources Used: BioModels models and KEGG pathways

Current Research


This site is a clone of PathCaseSB site mentioned above and instead of hosting BioModels models, it hosts SBML Test Suite models.




This system, currently being developed by a grant from NSF Biology, features mammalian metabolic pathways and computational tools designed for metabolomics analysis. Towards this end, PathCaseMAW database contains a fully hierarchically compartmentalized metabolic network for mammalian (humans and mice).

Data Sources Used: Mamalian pathways from literature.

This system features KEGG metabolic pathways. That is, it contains in its database, KEGG metabolic pathways. KEGG pathways data in PathCaseKEGG database is refreshed annually every year, via a license from KEGG.

Data Sources Used: KEGG Pathways

This system is the gateway to sister PathCaseMAW sites of three reconstructed metabolic networks.The data is from different sources of literature for different organisms and different models.





This system features sample pathways from the literature, and is no longer updated.

Data Sources Used: Literature
