ChEBI
Chemical Entities of Biological Interest, also requested as ChEBI, is the chemical database as alive as ontology of molecular entities focused on 'small' chemical compounds, that is factor of a Open Biomedical Ontologies OBO attempt at the European Bioinformatics Institute EBI. The term "molecular entity" indicated 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 impeach are either products of variety or synthetic products which throw potential bioactivity. Molecules directly encoded by the genome, such(a) as nucleic acids, proteins as alive as peptides derived from proteins by proteolytic cleavage, are not as a rule talked in ChEBI.
ChEBI uses nomenclature, symbolism together with terminology endorsed by the International Union of Pure & Applied Chemistry IUPAC and nomenclature committee of the International Union of Biochemistry and Molecular Biology NC-IUBMB.
