Hi Anne, The ChEBI common names are correct for both compounds since its based on an old numbering system for mitomycins as shown in Figure 1 of the following article...

Hi Anne, I've realized that we have separate entries for ribonucleoside 5'-monophosphate (CHEBI:37010), diphosphate (CHEBI:37075) and triphosphate (CHEBI:37076). I am not exactly sure why generic chemical structures have been added...

Historically, coordination bonds have been depicted in a variety of ways but IUPAC recommends that these bonds should be depicted as regular 'plain' bonds as shown in CHEBI:26355 (see other...

5 new ChEBI entries now created (I will try and add the child classes to these entries sometimes next week). polyfluoroalkyl substance (CHEBI:172406) perfluoroalkyl substance (CHEBI:172397) glycol ether (CHEBI:172390) brominated...

Thanks. I have added this issue to our workplan so the issue can be fixed during ChEBI 2's development.

In ChEBI, we form cross-references to other databases based on exact synonym and structure matching. The reason why the MetaCyc x-ref is added to both glycine zwitterion and glycine entries...

@cmungall. The roles in ChEBI are currently assigned based on evidence found in the primary literature (peer reviewed articles). In the past, we may have added the _has_role_ metabolite relationship...

Hi Chris, I don't think this would be feasible and our user community is diverse (consisting of both biologists and chemists). Some of our users are interested in the type...

Thanks. We are currently redeveloping ChEBI and this is something we can definitely take a look at and fix in the new system.

Hi Anne, I think LipidMaps may have got the structure wrong since the the structure of this compound should be based on the structure of leukotriene E4 which has an...
