[Ontology-editors] small molecule metabolism

[Midori Harris]

Hi,

Val has asked about adding a term to group small molecule metabolism 
separately from macromolecule metabolism. The initial request came a few 
months ago, and has been reiterated today. We've been hung up on how such 
a term could be named and defined, since "small molecule" is kind of a 
woolly concept that is hard to map onto, say, one branch of ChEBI.

Does anyone have any clever ideas for the ontology? Or are there tools 
that could help with Val's genome-wide analysis using the existing GO 
graph?
