MAC: PD,SW Chemical formula drawing, where ?

[Thorsten Becker]

Hi,


	I am looking for a shareware/freeware/PD software for the Mac to draw
complicated chemical formula. I know of something like "ChemEdit", but
it does apparently only accept single atom substituents at a C-atom
ring. "ChemDrawNet" is very advanced, but the student's version does
allow one only to VIEW formulae, no word about saving. 
	
	Thanks for your help

Thorsten
