The ontology clearly says that food component is a physiological role so what's the point in having role as a suffix? To change 'food component' to 'food component role' will...

I agree with you with regards to the ChEBI definitions. I have therefore updated the ChEBI definitions for food (CHEBI:33290) and food component (CHEBI:78295) so that the user knows that...

@cmungall I agree with you – there are a lot of inconsistencies in the way the ChEBI hierarchy is built for the neutral and ionised molecules. At the database level,...

Thanks Chris for bringing this to our attention. We will implement this when we start working on the new curator tool for ChEBI (hopefully in the next few weeks).

Some of these charge inconsistencies are related to structures containing R-groups. This can be dealt with by having a comment in the charge section saying the Net Charge excl. R...

Hi @cmungall A quick solution would be to completely remove the charge field from all the parent classes that contain structures with R-groups. Will this be acceptable to you?

If the terms are already present in ChEBI, then i can always add in the missing links if you send me a list with the missing is_a terms for the...

@cmungall With regards to adding the missing links - its seems that i have to go through the ChEBI hierarchy in order to see where the missing links are for...

@kaxelsen Do you know what the correct structure of cyathin A3 is? CAS (https://commonchemistry.cas.org/detail?cas_rn=38598-35-5&search=38598-35-5) and several other articles (PMID: 19387500, PMID: 20714781) show a completely different structure with an ether...

Hi Harold, You're right that NAD+ should also come under the class 'purines' but looking at the ontology of nucleotides in ChEBI, there seems to be quite a few historical...
