The Serum Metabolome database is a free web database about small molecule metabolites found in human serum and their concentration values. The database includes chemical data, clinical data and molecular/biochemistry data from literature and experiment. This database also references many other databases, such as KEGG, PubChem, MetaCyc, ChEBI, PDB, Swiss-Prot, GenBank, and Human Metabolome Database (HMDB).
The Serum Metabolome database is maintained by David S. Wishart.
The Serum Metabolome database protocol is available via its website.
