The term "molecular entity" refers to any "constitutionally or isotopically distinct [[atom]], [[molecule]], [[ion]], [[ion pair]], [[Radical (chemistry)|radical]], [[radical ion]], [[complex (chemistry)|complex]], [[conformer]], etc., identifiable as a separately distinguishable entity"<ref>{{GoldBookRef|title=molecular entity|file=M03986}}</ref>. The molecular entities in question are either products of nature or synthetic products used to intervene in the processes of living organisms. 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 [[IUPAC nomenclature|nomenclature]], symbolism and terminology endorsed by the [[IUPAC|International Union of Pure and Applied Chemistry]] (IUPAC) and Nomenclature Committee of the [[International Union of Biochemistry and Molecular Biology]] (NC-IUBMB).
