ChEBI

Chebi may refer to: * ChEBI, Chemical Entities of Biological Interest * Chebi Khan (fl. 630-650), a claimant of the title of khan of Eastern Turkic Khaganate after the collapse of Xueyantuo * Chebi, Ethiopia, a town in Jeldu woreda, Ethiopia * Typhoon Chebi (2001) * Typhoon Chebi (2006) * Chebi, an English name for the Russian character Cheburashka

Chemical Entities of Biological Interest, also known as ChEBI, is a chemical database and ontology of molecular entities focused on "small" chemical compounds, that is part of the Open Biomedical Ontologies (OBO) effort at the European Bioinformatics Institute (EBI). The term "molecular entity" refers to any "constitutionally or isotopically distinct atom, molecule, ion, ion pair, radical, radical ion, complex, conformer, etc., identifiable as a separately distinguishable entity". The molecular entities in question are either products of nature or synthetic products which have potential bioactivity. Molecules directly encoded by the genome, such as nucleic acids, proteins and peptides derived from proteins by proteolytic cleavage, are not as a rule included in ChEBI. ChEBI uses nomenclature, symbolism and terminology endorsed by the International Union of Pure and Applied Chemistry (IUPAC) and nomenclature committee of the International Union of Biochemistry and Molecular Biology (NC-IUBMB).
