The Analytical Chemistry Springboard Umea University, Sweden

Pages vary widely in how recently they were updated, but this is considered one of the primary analytical chemistry gateway sites.

BRENDA

Developed and maintained at the Institute of Biochemistry at the University of Cologne, BRENDA is a database of enzyme functional data for approximately 3,500 enzymes. Searchable by enzyme names and synonyms, E.C. (Enzyme Commission) number, CAS Registry Number, reaction and reaction type, organism, substrate, etc. Providing data, literature references, and commentary on strain and database sources.

ChemInfo

Created by Gary Wiggins, this site has long been considered one of the very best places to start when looking for a well-organized and thorough approach to chemical information -- on the Web and in print. Under the Resource Guides button, look for SIRCh ("Selected Internet Resources in Chemistry") for a carefully evaluated selection of Web resources.

Heterocycles Database: natural products with heterocyclic ring systems

Natural products with heterocyclic rings systems for which structures have been determined or synthesized since 1975. The major journals are surveyed. The database is divided into synthesis and structure sections.

Chemistry Central
          Published by BioMedCentral, long a leader in providing access to open access, peer-reviewed literature for biology, the
          Chemistry Central gateway represents a major move in this direction for chemistry. Beilstein Journal of Organic Chemistry               and Chemistry Central Journal are just two of the journals provided here.

Links for Chemists

Part of the WWW Virtual Library, Links for Chemists offers easy navigation and a wealth of information under such categories as University Chemistry Department (in the U.S. and abroad), Companies/Industry, Chemical Literature, Chemical Information, and many subject-specific categories. One of the best.

Novel Antibiotics Database

Substances which were first reported in th Journal of Antibiotics (Japan Antibiotics Research Association).

Science.gov (Chemistry and Chemicals)

This is the recently redesigned gateway to scientific resources produced by the U.S. government. There are a number of important chemistry-related databases available here, including ChemWebBook, CHEMIDPlus, IRIS, CancerNet. etc. Many are searchable by compound name, CAS Registry Number, structure, etc.

WebReactions

A reaction database which searches particular bond changes, rather than whole molecules, allowing for more efficient searching of the more than 1 million reactions contained. Developed by Prof. James Hendrickson, Brandeis University.
