Rhea Download

How to download Rhea records?

Rhea Download fetches expert-curated biochemical reaction records by Rhea ID. It returns RDF files and reaction metadata such as the equation and EC numbers when available.

Use this tool when you need reaction records for enzyme annotation, pathway work, reaction databases, or reproducible biochemical identifiers.

Supported Rhea downloads

Understanding the results

The results panel lists the RDF file as a downloadable item. The Details tab records the database, Rhea ID, reaction title, file label, format, source type, filename, and URL.

Filenames follow the pattern:

rhea-10000-rdf.xml

The provider accepts IDs with or without the RHEA: prefix. The output metadata keeps the normalized reaction identifier.

Common use cases

• Download reaction records for enzyme annotation.
• Store Rhea RDF files with pathway analysis results.
• Cross-reference EC numbers and reaction equations.
• Keep stable reaction identifiers alongside protein analysis outputs.

FAQ

What is Rhea used for?

Rhea is a curated resource for biochemical reactions. It is useful when you need precise reaction definitions for enzymes, metabolites, and pathways.

Can I search by reaction text?

The broader database search page supports reaction queries. This download tool is designed for direct Rhea ID retrieval.

Why is the file extension .xml?

The RDF download is serialized as XML, so the result uses an .xml extension for compatibility with XML/RDF tools.
