ChemConnections
ChemConnections maintained by Berkeley. Provides a 3_D viewer for downloading. Also links to protein/amino acid databases.
Molecules R’Us
Molecules R’Us. Searches the Brookhaven protein data bank.
ChemFinder
ChemFinder by Cambridge Soft. A remarkably efficient Internet search engine, which searches for information on specific compounds by name, formula, CAS registry number, and molecular weight. Provides synonyms, CAS numbers, physical property data (i.e. molecular weight, melting point, boiling point, specific gravity, etc.) and 2D chemical structures on the ...
General Chemistry Online
