The Human Metabolome Database (HMDB) is a freely available electronic database containing detailed information about small molecule metabolites found in the human body. It is intended to be used for applications in metabolomics, clinical chemistry, biomarker discovery and general education.HMDB is supported by David Wishart, Departments of Computing Science & Biological Sciences, and University of Alberta. HMDB is also supported by the MetabolomicsInnovation Centre, a Genome Canada-funded core facility serving the scientific community and industry with world-class expertise and cutting-edge technologies in metabolomics.
Recently announced version 3.0 of the HMDB has been significantly expanded and enhanced over the 2009 release (version 2.0). In particular, the number of annotated metabolite entries has grown from 6500 to more than 37,166. This enormous expansion is a result of the inclusion of both “Confirmed” metabolites (those with measured concentrations or experimental confirmation of their existence) and “Expected” metabolites (those for which biochemical pathways are known or human intake/exposure is frequent but the compound has yet to be detected in the body). The latest release also has greatly increased the number of metabolites with biofluid or tissue concentration data, the number of compounds with reference spectra and the number of data fields per entry. In addition to this expansion in data quantity, new database visualization tools and new data content has been added or enhanced.
