| *Background*
Appearing in a wide variety of contexts, biochemical 'small molecules' are a core element of biomedical data. Chemical ontologies, which provide stable identifiers and a shared vocabulary for use in referring to such biochemical small molecules, are crucial to enable the interoperation of such data. One such chemical ontology is ChEBI (Chemical Entities of Biological Interest), a candidate member ontology of the OBO Foundry. ChEBI is a publicly available, manually annotated database of chemical entities and contains around 18000 annotated entities as of the last release (May 2009). ChEBI provides stable unique identifiers for chemical entities; a controlled vocabulary in the form of recommended names (which... |

| ChEBI (Chemical Entities of Biological Interest) is a database of ‘small’ molecular entities structured around a chemical ontology. It contains almost 600,000 entries, of which approximately 20,000 have been manually curated, as well as entries for groups (parts of molecular entities) and classes of entities. It provides a wide range of information such as chemical nomenclature, structures and related chemical values, and establishes interrelationships between entities in the ontology, in terms of both structure and role. ChEBI places a strong focus on quality, with exceptional efforts being applied to upholding IUPAC nomenclature recommendations and best IUPAC practices when drawing chemical structures.... |

| *ChEBI background:* Chemical Entities of Biological Interest (ChEBI) is a curated database of small chemical entities important in biosystems. As well as a description of entities, it provides a semantically rich knowledge base; and an internal hierarchy that organises the entities by their molecular structure types and potential rôles.

*The ChEBI-IEDB collaboration:* The Immune Epitope and Analysis Resource (IEDB) is a project supported by contract from the National Institute of Allergy and Infectious Diseases (NIAID). Its goal is to make epitope-related data on infectious diseases and immune disorders freely available to researchers worldwide. In June 2009, ChEBI began working with the IEDB on a project aimed... |
