Pathway ontology

The Pathway Ontology captures information on biological networks, the relationships between netweorks and the alterations or malfunctioning of such networks within a hierarchical structure. The five main branches of the ontology are: classic metabolic pathways, regulatory, signaling, drug, and disease pathwaysfor complex human conditions.
