The Madison Metabolomics Consortium Databa … The Madison Metabolomics Consortium Database (MMCD) supports high-throughput NMR and MS approaches to the identification and quantification of metabolites present in biological samples. It works in conjunction with the Madison Metabolomics Consortium Database is a resource for metabolomics research based on nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS).<br />
MMCD currently serves as a hub for information on small molecules of biological interest gathered from electronic databases and the scientific literature. Each metabolite entry in the MMCD is supported by information in an average of 50 separate data fields, which provide the chemical formula, names and synonyms, structure, physical and chemical properties, NMR and MS data on pure compounds under defined conditions where available, NMR chemical shifts determined by empirical and/or theoretical approaches, calculated isotopomer masses, information on the presence of the metabolite in different biological species, and extensive links to images, references, and other public databases, such as the Kyoto Encyclopedia of Genes and Genomes (KEGG) and PubChem. The MMCD search engine supports versatile data mining and allows users to make individual or bulk queries on the basis of experimental NMR and/or MS data plus other criteria.<br /> r MS data plus other criteria.<br />
