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.... |
