    The molecule of the day is: Acetic acid

    Acetic acid is a very commonly used molecule; also known as vinegar. It adds the delightful tart or sour flavor to many foods and drinks, such as wine and pickles. Acetic acid can improve the palatability or add interesting qualities to many different foods. For example, it is quite easy to make sour milk curds with some vinegar, and it is frequently used in food processing. Clearly it is safe to consume in dilute solution, and due to its acidic nature, it creates an environment that is difficult for many hostile microrganisms to survive in. In spite of its many excellent qualities, it is marked as corrosive in the glacial or concentrated solution. The fumes can be rather shocking and odious on inhalation, and it should be handled with care and correct ventilation. It is a superb mildly acidic buffer for the lab, and it is commonly used for that purpose.

    updated Fri Aug 29 14:39:14 EDT 2008

    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.

    updated Tue Aug 26 19:27:29 EDT 2008

    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. 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. 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,, with gdmolecules in the subject line. Cheers!
