|Alkalinity Calculator (or.water.usgs.gov)The source of information about alkalinity and the procedures to measure it.|
|American Mineralogist Crystal Structure DatabaseThis site is an interface to a crystal structure database that includes every structure published in the American Mineralogist, The Canadian Mineralogist, European Journal of Mineralogy and Physics and Chemistry of Minerals, as well as selected datasets from other journals. The database is maintained under the care of the Mineralogical Society of America and the Mineralogical Association of Canada, and financed by the National Science Foundation.|
|Biocatalysis-Biodegradation Database (umbbd.msi.umn.edu)This database contains information on microbial biocatalytic reactions and biodegradation pathways for primarily xenobiotic, chemical compounds. The goal of the BBD is to provide information on microbial enzyme-catalyzed reactions that are important for biotechnology. University of Minnesota.|
|CAS Source Index (CASSI) Search Tool (cassi.cas.org/search.jsp) ► A resource for scientists and library workers who need a reliable bibliography information. It enables one to determine or to confirm journal titles and abbreviations that are included in Chemical Abstracts Service (CAS) Indexes from 1907.|
|ChemDB Web Interface Index (omictools.com/chemdb-tool)Provides access to about 5M commercially available small molecules. ChemDB is a chemical database that contains data coming from the electronic catalogs of over 150 chemical vendors as well as a limited number of publicly available datasets. The database includes search tools in support of systems biology and drug discovery projects. Data can be searched by structural similarity, includes several, names and annotations and users can also search virtual chemical space.|
