The Comparative Toxicogenomics Database (CTD) presents scientifically reviewed and curated information on chemicals, relevant genes and proteins, and their interactions in vertebrates and invertebrates. It integrates sequence, reference, species, microarray, and general toxicology information to provide a unique centralized resource for toxicogenomic research. The database also provides visualization capabilities that enable cross-species comparisons of gene and protein sequences.
This resource is a provider. This means that
while it may have its own prefix, it actually reuses the identifiers provided by the
mesh
prefix. For all use cases, you should use mesh
instead of ctd.chemical
.
ctd.chemical
Local identifiers in CTD Chemical should match this
regular expression:
^[CD]\d+$
Compact URIs (CURIEs) constructed from CTD Chemical should match
this regular expression:
^ctd\.chemical:[CD]\d+$
The metaregistry provides mappings between the Bioregistry and other registries. There are 4 mappings to external registries for this resource with 1 unique external prefixes.

Providers are various services that resolve CURIEs to URLs. The example CURIE
None:D001151
is used to demonstrate the provides available for
this resource. Generation of OLS and BioPortal URLs requires additional programmatic
logic beyond string formatting.
