Worldwide repository for small-molecule crystal structures/3D atomic coordinate data. Not available in the library, but contact wiswellj@appstate for access.

Provides access to information on the biological activities of small molecules. It is organized as three linked databases within the National Center for Biotechnology Information (NCBI) Entrez Information retrieval system: PubChem Substance: Search chemical substance records using names, synonyms, or keywords.
PubChem Compound: Search chemical compounds using names, synonyms, or keywords.
PubChem BioAssay: Search via terms one would expect to find in the description of a bioassay of interest.

This site provides, at no charge, a repository of information related to chemical structures and other associated information. It includes more than 18 million chemical structures.
