However, in the broader context of bioactive chemistry, it becomes indivisible from the related domains of chemical biology (directed towards mechanistic insight rather that direct drug discovery), enzymology, pharmacology, toxicology (as the wrong sort of bioactivity) in addition to the development of insecticides or herbicides  Connectivity: This term is used for an explicit link (e.g. a URL pointer) between a published document and the chemical structures specified in it. Implicit is not only manual navigation (e.g. link-clicking) but also that such connectivity can be made machine-readable and thus computationally interrogated at large scale via an Application Programming Interface (API) or a Resource Description Framework (RDF).
