Searching and getting data from ChEBI

Searching ChEBI

Quick search

Simply type the term (e.g. cholesterol), formula (e.g. C6H12O6), registry number (e.g. 64-17-5), InChI (IUPAC International Chemical Identifier, e.g. InChI=1/H2O/h1H2) or ChEBI identifier (e.g. 30815) into the search box on the ChEBI home page, then click on the 'Search ChEBI' button or press 'Enter' on your keyboard.

Wildcards (*) can be used to search using a partial name; e.g. searching for cholest* will find all those entities which have a name or synonym starting with 'cholest', such as cholesterol and cholesteryl β-D-glucoside.

Advanced search

From the Advanced Search page (accessed from the menu in the top left-hand corner of any ChEBI page) searches can be performed using several terms at once or restricted to specific fields (e.g. ChEBI name, synonym, formula).

Structure-based searches can be performed by drawing or loading a chemical structure and the search can be further restricted by combining with a term-based search.
