Biochemical Pathways provide an overview of the chemical reactions of cells in various species and organs. Dr. Michal first compiled the Pathways Chart in 1965 and has been fine-tuning it ever since. Today, and with the collaboration of Roche, the two enormous posters can be found hanging in just about every research institute from Argentina to New Zealand.

You have to be someone with tenacity, patience and a love for science.”
Dr. Gerhard Michal Editor of the Roche Biochemical Pathways

First compiled in 1965 by Dr. Gerhard Michal, the Roche wall charts have been published as printed posters in several editions. Spanning two enormous posters, they provide a graphical overview of the most important biochemical pathways all in one place.

If you think could contribute or collaborate with us (e.g. provide an interface to an enzyme database like ExPASy ENZYME) we look forward to hearing from you.
