Silicon dioxide is probably the most common form of the versitile silicon atom that is found naturally. It is also known as glass, quartz, crystal rose, silica, and common sand, so that it can be quite lovely and useful indeed! According to Wikipedia, silicon dioxide is the most abundant mineral on the earth, and it is probably true that there are buckets of the stuff nearby for free. Goes to show. Our silicon gallery is full of the many interesting and useful molecules that are based on silicon, and it is worth a look. One that we do not have ready as of yet is silicon carbide, an important ceramic material. There is likely some confusion around the name, because silicate, also known as silica gel, is useful in the lab as a dessicant, sometimes changing from light blue to pink on hydration. Silicate could also be called silion trioxide, because it has three bonded oxygens in contrast to the molecule at right.

Added Molscript graphics and MOD desktop image to the right sidebar. The theme is infinite carbon chain. The code is in infrastructure. The other main molecular graphics programs in use at this time are RasMol, Rester3D, PyMOL, and PovChem. The viewer is xzgv, and ImageMagick for touch up; mainly mogrify and convert. Please feel free to send any questions along.

We continue to get encouragment to provide coordinate files with improved geometry, although this is a computationally intensive task which is down the road still. Meanwhile, a few supurb 3-dimensional structures are already found in the archive, and two of them have been featured in the right sidebar today. If you rummage around in the MOD galleries, you are likely to find more 3D coordinate files, as well as some very interesting 2D representations! In our opinion, many of the most interesting molecules have planar geometry, so that the current files are quite useful. In due course, we plan to provide a comprehensive collection of coordinate files with good stereochemical geometry, all in the selfsame spirit of free and open source software and public access. We welcome any and all input.

Our new directory style was featured in a the right sidebar of the Jasmone MOD page today. Just click the directory link from the top page or in any of the recent galleries to view this new feature. These pages typically include links to the source databases, which often have chemical diagrams or useful additional information about the molecules. A smiley code is currently featured at the bottom of each page. Smile.

Added quick navigation links to the left side bar. The site has reached 111 GB, and a massive backup is underway. We are still just getting started.

Added developer links to the left side bar.

I have automated the process to make molecule galleries, which I am finding very useful to my research, so I thought that I would share the opportunity and take requests. It is quick and easy. I did a bisphenol search today, and as I expected, the search turned up a few stilbenes, which is the same molecular family as resveratrol. Strikingly, Bisphenol A is a noted teratogen, which shows that care must be taken when using such molecules during pregnancy, nursing, and development. Here is a link to the bisphenol gallery.

If you would find it useful, I am definitely interested in taking requests for molecule galleries. Just send me the name of your favorite molecule. As you may be able to tell, we have access for galleries to about 1% or 0.5 million structures, in the total archive thus far, but it is already quite useful. The automated jobs are underway to fill in the rest. The next milestone is the capability to index and make galleries for the remaining millions of molecules for which we have pdb files already, which would be 5-10% complete. Any comments or suggestions are also welcome.

A terminal screenshot has been added to the right sidebar, in order to show the kind of code that is being used to generate the Molecules directory indices. All inquiries and suggestions are welcome.

Reaction to our website has been quite positive and encouraging, but people are anxious to see structures with improved stereochemistry. We have received many suggestions about how to make that happen faster. For the time being, we are experiencing the best structure viewing results with RasMOL. Name extraction and structure file linking jobs are underway, which is an indication that we are still in a preliminary phase. Google spiders more almost everyday, and past experience indicates that the search capability will become very useful indeed! Here is some secret mumbo jumbo. I'm afraid that my Japanese or Korean is broken at best ;-}. Enjoy!

An RSS News Feed has been added to the right side bar.

Several new indices have been added to our sidebar, notably; current index by name, and gallery by name. These are large indices, but also vastly incomplete, and work is underway to improve them. A list of bloggers who have mentioned the site, with links in their blogs, is now in the front sidebar, although only one is known thus far. Due to the vastness of the scale, many of these things will be divided out and buried a little deeper eventually, but they can be showcased now, and they are a good survey.

Some facts: The Molecules website contains more than 4 million small molecule structure files in pdb format, and molecular graphics representations. About 50 million molecules are still in the pipe, and they are expected to appear here over the course of the next few weeks and months. The pdb format is readable by common FOSS molecule viewer software, such as RasMol and PyMOL. In due course, we plan to provide high quality structures via energy minimization refinement, and additional resources.

Molecules@gnu-darwin.org is founded in the spirit of free software, open source, and public access. It is hoped that access to these files will be a wonderful community resource for science education, research, and entertainment as well. We are looking for investment, funding, or sponsorship in order to expedite and expand this work, and lead the field, with an eye towards an advanced, complete, synthetic, structural, and informatical bioorganome. Meanwhile, the site is already an exceptional lab resource, and molecular catalog, providing the means and building blocks towards additional novel structures. We aim to be the best.

The structural biology, protein crystallography, and molecular graphics talent that is building the Molecules archive is available to work for you in a contract or consulting arrangement. Wide-ranging expertise is available. Molecules@gnu-darwin.org is built entirely with FOSS, free and open source software, GNU-Darwin OS, and it is under the aegis of The GNU-Darwin Distribution. Here is a link to the Distribution résumé. Our founder is an X-ray laboratory admin for the Department of Biophysics and Biophysical Chemistry of Johns Hopkins University School of Medicine. You can also read his CV. We would like to build a community around this website, and we are looking for volunteers and collaborators to help. Regarding any aspect of the work of this site, please feel free to contact us, molecules@gnu-darwin.org, with gdmolecules in the subject line. Cheers!
