Help:WikiPathways Metabolomics
From WikiPathways
On this page we collect SPARQL queries to see the state of the Metabolome in WikiPathways. Triggered by User:Andra's RDF / SPARQL work, curation started with metabolites without database identifiers. But this soon led to the observation that metabolites are often not even annotated as being a metabolite (using <Label> rather than <DataNode>). Therefore, User:Egonw started at Pathway:WP1 to curate them one by one and fix these issues:
- connect lines between metabolites
- convert metabolites to use <Label> rather than <DataNode>
The reason for this is that these are some basic underlying properties we need for metabolomics research fields.

Metabolome
The following queries provide an overview of the Metabolome captures by WikiPathways.
The key type for metabolites is the wp:Metabolite. We can see all available properties with:
prefix wp: <http://vocabularies.wikipathways.org/wp#>
select distinct ?p where {
?mb a wp:Metabolite ;
?p [] .
}
