Can we import pubchem CID molecules to model proteins with lipids? Would be very cool.

Hi Alexander, The recommended address for asking ChimeraX questions is the chimerax-users@cgl.ucsf.edu <mailto:chimerax-users@cgl.ucsf.edu> mailing list CC'd here, see "contact us" on our website or in the ChimeraX menu: <https://rbvi.ucsf.edu/chimerax/docs/contact.html> If PubChem Compound has the coordinates, you can open them in ChimeraX by CID, e.g. command open pubchem:12123 - OR - open 12123 from pubchem ... as explained here <https://rbvi.ucsf.edu/chimerax/docs/user/commands/open.html#fetch> ...or with menu: File... Fetch by ID, choosing the Pubchem option and specifying the CID in the dialog: <https://rbvi.ucsf.edu/chimerax/docs/user/fetch.html> However, not every entry in PubChem Compound has coordinates available, so I don't know if it will work for your specific molecules of interest. I hope this helps, Elaine ----- Elaine C.
