from the Web page and the Freshmeat listing: XDrawChem is a program for drawing chemical structures in two dimensions. It comes with a library of amino acids and nucleic acids. It can read and write MDL Molfiles, read and write CML (Chemical Markup Language), read (some?) ChemDraw XML and binary files, and export to EPS. It can predict 13C NMR and simple IR spectra. It works under Unix or Windows.
