What is PubChem?

PubChem is a free chemical database and an open archive of the biological activities of millions of substances. PubChem is a part of the National Center for Biotechnology Information (NCBI), a division of the U.S. National Library of Medicine. PubChem provides information on the biological activities of small molecules. PubChem is organized as three linked databases within the NCBI’s Entrez information retrieval system. These are PubChem Substance, PubChem Compound, and PubChem BioAssay. PubChem also provides a fast chemical structure similarity search tool.

Links from PubChem’s chemical structure records to other Entrez databases provide information on biological properties. These include links to PubMed scientific literature and NCBI’s protein 3D structure resource. Links to PubChem’s bioassay database present the results of biological screening.

PubChem recently started a blog, as well as accounts on Twitter, FaceBook, and Google+ to post information about new PubChem features and data updates.
