Purpose:When wefirst consider the structure of organic molecules, most of us realize thatthree-dimensional structure is both supremely important and sometimes hard tovisualize.Once upon a time, everyorganic chemistry student was encouraged to buy a small set of molecular models(wood, metal or plastic) to help learn the characteristic shapes of all thosecurious combinations of sp2 and sp3 hybridizations.Biochemists built elaborate (and sometimesquite lovely) 3D models of their favorite proteins.Nowadays, molecular modeling software isavailable for the same purposes.
Molecular viewing software should allow you to easily createmolecules (or load them from a variety of file formats), optimize the geometryif needed, then display the structures in a variety of formats: “ball andstick” and “wire frame” mimic some of the older wooden and metal models, whilesemi-transparent electron density formats provide information not availablefrom physical model kits.Most packagesalso allow the color coding or labeling of atoms (or residues) and automaticrotation of the image to fool the eye into seeing 3 dimensions on a flatdisplay screen.

Chemistry Drawing Software. ConceptDraw DIAGRAM extended with Chemistry solution from the Science and Education area is a powerful chemistry drawing software that provides the useful tools to help you design all kinds of chemistry drawings and illustrations, chemical schemes and diagrams of formulas, reaction schemes and lab set-ups of any complexity.
Organic Chemistry Sorrell Pdf Free Software Programs online, freeWord To Pdf Free SoftwareOn the other hand, if you want to look at larger molecules, the Molegro Molecular Viewer from Molegro Bioinformatics is a good choice. Like ChemSketch, the Molegro viewer is commercial freeware with an easy-to-use interface and good quality graphics. It cannot be used to build molecules, but macromolecules can be imported using a variety of file formats, including MDL, Sybyl and protein data bank (.pdb). Since the viewer is designed to help analyze interactions between small molecules (ligands) and macromolecules, it should be especially useful for drug interactions and docking. The Molegro viewer is available for Windows, Mac and Linux operating systems. Two other programs which may be useful to more advanced students are the open source molecular viewer and editor Avogadro and the more advanced commercial freeware program Discovery Studio Visualizer. Additional information on these programs can be found in the Resource pdf attachment (below). Last updated July 18,2011 Convert Word To Pdf Free SoftwareComments are closed.
