Definition of precursor in English English dictionary: That which precurses, a forerunner, a predecessor, an indicator of approaching events; One of the compounds that participates in the chemical reaction that produces another compound; a forerunner or herald; {n} a forerunner, harbinger, courier; An air pressure wave which moves ahead of the main blast wave for some distance as a result of a nuclear (or atomic) explosion of appropriate yield and low burst height over a heat-absorbing (or dusty) surface The pressure at the precursor front increases more gradually than in a true (or ideal) shock wave, so that the behavior in the precursor region is said to be nonideal See Blast wave, Shock front, Shock wave; starts a chain reaction which accelerates growth; a person who goes before or announces the coming of another a substance from which another substance is formed (especially by a metabolic reaction); A substance that precedes, and is the source of, another substance; In photochemistry, a compound antecedent to a pollutant For example, volatile organic com- pounds (VOCs) and nitric oxides of nitrogen react in sunlight to form ozone or other photochemical oxidants As such, VOCs and oxides of nitrogen are precursors; the reactants used in industrial semiconductor manufacture to make the desired product; for instance, ArH3 is often the precursor for the Arsenic in GaAs devices; a substance from which another substance is formed (especially by a metabolic reaction); The chemical element that changes due to enzymatic or physical pressure; A precursor of something is a similar thing that happened or existed before it, often something which led to the existence or development of that thing. He said that the deal should not be seen as a precursor to a merger. something that happened or existed before something else and influenced its development precursor of/to (praecursor, from praecurrere ); Any directly emitted pollutant that, when released into the atmosphere, forms or causes to be formed or contributes to the formation of a secondary pollutant for which an ambient air quality standard has been adopted, or whose presence in the atmosphere will contribute to the violation of one or more ambient air quality standards; For carbon fibers, the rayon, PAN or pitch fibers from which carbon fibers are made; A chemical compound which is released into the atmosphere, undergoes a chemical change, and leads to a new (secondary) pollutant VOCs are precursors to ozone; Any chemical reactant which takes part at any stage in the production by whatever method of a toxic chemical; a substance that is used as a building block for another; One who, or that which, precedes an event, and indicates its approach; a forerunner; a harbinger; {i} precedent, antecedent; predecessor (in a job or position); herald or harbinger; announcer, crier; Either the PAN or pitch fibers from which carbon and graphite fibers are derived; an indication of the approach of something or someone; A substance or condition whose presence generally precedes the formation of another, more notable, condition or substance; A module, the study hours of which a student shall be required to have completed in order to proceed to a subsequent specified module or modules, but for which credit may not necessarily have been awarded; compounds that change chemically or physically after being emitted into the air and eventually produce air pollutants For example, organic compounds are precursors for ozone; In photochemistry, a compound antecedent to a volatile organic compound (VOC) Precursors react in sunlight to form ozone or other photochemical oxidants; -a substance that precedes, and is the source, of another substance; for instance, 5-HTP is the precursor to serotonin; a person who goes before or announces the coming of another; a chemical which can be converted to another is a precursor of the latter; For carbon fibers, the rayon, PAN, or pitch fibers from which carbon fibers are made; A chemical that precedes another in a series of metabolic breakdowns; a substance that precedes another substance; or a substance from which another substance is made; in food supplements, the precursors to neurotransmitters in particular are sometimes preferred; In a metabolic sequence of reactions, a compound that gives rise to the next compound: for example, choline is the precursor for the neurotransmitter acetyicholine; Chemicals that, when combined with other chemicals, form a chemical warfare agent compound [140]
