Chemical Entities of Biological Interest (ChEBI) is a freely
available dictionary of molecular entities focused on ‘small’ chemical
compounds. 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 used...

Chemical Entities of Biological Interest (ChEBI) is a freely
available dictionary of molecular entities focused on ‘small’ chemical
compounds. 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 used to intervene in the
processes of living organisms.
ChEBI encompasses an ontological classification, whereby the
relationships between molecular entities or classes of entities and
their parents and/or children are specified.
ChEBI uses nomenclature, symbolism and terminology endorsed by the following international scientific bodies:
- International Union of Pure and Applied Chemistry (IUPAC)
- Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (NC-IUBMB)
Molecules directly encoded by the genome (e.g. nucleic
acids, proteins and peptides derived from proteins by cleavage) are not
as a rule included in ChEBI.
