Golm Metabolome Database (GMD)
(GMD) facilitates the search for and dissemination of reference mass spectra from biologically active metabolites quantified using gas chromatography (GC) coupled to mass spectrometry (MS). GC/MS profiling studies aiming at the identification of compounds from complex biological mixtures depend on the comparison of observed mass spectra and retention times with reference libraries such as the GMD. The GMD comprises mass spectra and retention time indices of pure reference substances and frequently observed mass spectral tags (MST: mass spectrum linked to chromatographic retention) of yet unidentified metabolites
Human Metabolome Database (HMDB)
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. The database is designed to contain or link three kinds of data: 1) chemical data, 2) clinical data, and 3) molecular biology/biochemistry data. The database contains 220,945 metabolite entries including both water-soluble and lipid soluble metabolites. Additionally, 8,610 protein sequences (enzymes and transporters) are linked to these metabolite entries.
