http://pontotriplo.org/triplepoint A selection of posts from Ponto Triplo - a Portuguese blog with links to the best chemistry sites, news and events Sun, 19 Apr 2009 23:15:30 +0000 en hourly 1 http://wordpress.org/?v=3.3.1 http://pontotriplo.org/triplepoint/2005/02/mol4d_web_organ.html http://pontotriplo.org/triplepoint/2005/02/mol4d_web_organ.html#comments Thu, 10 Feb 2005 00:27:00 +0000 Jorge Goncalves http://pontotriplo.org/triplepoint/?p=93 ]]> Mol4D – Molecules in four dimensions – is a general and organic chemistry educational web site. Interactive tutorials with animated molecules and an online editor to build molecules, perform conformational analysis or model some reactions. Very good.

In this site one can find how to (and the software needed to) access the database.

Still in development, it contains valuable data for an appreciable amount of compounds of biological interest. In their own words: ChemBank is a freely available collection of data about small molecules and resources for studying their properties, especially their effects on biology. It is being developed to assist biologists who wish to identify small molecules that can be used to perturb a particular biological system and chemists designing novel compounds or libraries, and serve as a source of data for cheminformatic analyses. The project is still in an early stage and we will be adding tools and data frequently.

For those who want to know better this kind of molecules, the Common Molecules Collection is the ideal place. The authors focused their attention on molecules studied in chemistry classrooms but this fascinating collection includes also molecules that might be of interest for the general public. For each molecule, its structure is presented together with some additional information. In this site, organized in a very elegant way, there is also helpful information about crystallography and crystallization.

The suggested links are worth a look, as well as this lesson (and the references herein).
