ChemDraw: a Versatile Molecule Sketching Tool for (Bio)Chemists

Have you ever wondered how to make professional, easy-to-understand figures of molecules for presentations or publications? While several programs exist for this purpose, ChemDraw is like the Swiss Army knife of chemical sketching programs that most chemists and journals use to prepare figures. Beyond the ability to create chemically accurate and legible figures, ChemDraw can…
