Europe PMC A database of biomedical and life sciences literature with access to full-text research articles and citation. Europe PMC includes resources from PubMed and PubMed Central (PMC), projects developed at the NCBI in the USA. Europe PMC is part of a network of PMC International (PMCI) repositories that also includes PMC Canada.
GMD - Gohn Metabolone Database The Golm Metabolome Database (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.
