Metabolic network reconstruction

Where metabolic networks come from (reconstruction) ? How they are stored ? How they can be mined using MetExplore ?

  • Use metabolic networks knowing how they are built and what is there content
  • Browse BioSource content in MetExplore

General knowledge on metabolism.


Metabolic fingerprints (list of metabolites of interest) identified using metabolomics can be put back in a biochemical context using metabolic networks. Metabolic networks aim at gathering all metabolic reactions an organism can perform. This section is dedicated to introduce the basic concepts undelrying genome scale metabolic network reconstruction. It will also provides some pointers towards repositories where metabolic networks can be found and used. Finally the course will present how metabolic network content can be browsed using MetExplore.


The slideshow will present concept and databases related to genome scale metabolic networks. Then it will give a quick overview of these networks in MetExplore.


This course allowed to understand how network are reconstructed and how they can be accessed. The course also introduced the concept of Biosource and how it can be browsed in MetExplore web server.
