HMDB

The Human Metabolome Database (HMDB) is a comprehensive resource for human metabolite data. Key features:

Contains detailed information about small molecule metabolites in humans Includes chemical, biological, and clinical data Provides spectral data (NMR, MS) Lists metabolite concentrations in various biosamples Contains information about metabolite-protein interactions Offers disease-metabolite associations Features metabolic pathway information

The database is maintained by the University of Alberta and serves as a reference for metabolomics research, clinical chemistry, and biomarker discovery.
