Human metabolism

Reactome's human metabolism drawn as one network. Each molecule has one home node; widely shared molecules also appear as dashed copies in other territories, linked from their details. .

Territories

Reading the map

Metabolite; its structure appears as you zoom in
Reaction, arrow toward the product
Cofactors and co-substrates are written beside the reaction when you zoom in
Dashed ring: a copy of a widely shared molecule or cofactor in another territory or pathway
Compartment transfer of the molecule it is linked to
Binding, release or complex event; its proteins are named in its details
Outline: reactions mostly in the mitochondrion

Arrows follow Reactome's curated reaction direction.
