Pathway databases

Definition

Pathway databases are specialized repositories that store and organize information about biological pathways, including metabolic and signaling pathways. These databases facilitate the analysis of complex biological processes by providing curated data, visual representations, and connections between different pathways, allowing researchers to study interactions, regulation, and the overall functioning of metabolic networks.
