For example, a chemical database might store a molecule with stereochemistry unspecified, whereas a chemical registry system requires the registrar to specify whether the stereo configuration is unknown, a specific (known) mixture, or racemic. Each of these would be considered a different record in a chemical registry system.
TRANSFAC: a database about eukaryotic transcription factors, their genomic binding sites and DNA-binding profiles; JASPAR: a database of manually curated, non-redundant transcription factor binding profiles. MetOSite: a database about methionine sulfoxidation sites and its functional roles in proteins [35]
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [1]
PubChem is a database of chemical molecules and their activities against biological assays.The system is maintained by the National Center for Biotechnology Information (NCBI), a component of the National Library of Medicine, which is part of the United States National Institutes of Health (NIH).
