I'm sorry if this is OT, but I find myself slowly going insane trying to draw common biomolecules such as Acetyl Coenzym A. The thing is, I just want to draw the acetyl part and then link that to a text that says "coenzym A" (or whatever), so something like this:
I have no need for the gigantic structure of actual Coenzyme A. I'm trying to visualize basic metabolic reactions such as the citric acid cycle etc. Having a 20-molecule-chain in every other step would just be distracting.
The software I've come across thus far don't support the typing part of the molecule as free text, they require me to pick an actual molecule from the periodic table. In the few cases where I can type text I can't have the molecule link to it.
Thus far I have tried chem4word 3.1 (only supports pre-defined functional groups), Pubchem sketcher 2.4, chemspace and Molview.
