Systematic biology (hereafter called simply systematics) is the field that (a) provides scientific names for organisms, (b) describes them, (c) preserves collections of them, (d) provides classifications for the organisms, keys for their identification, and data on their distributions, (e) investigates their evolutionary histories, and (f ...
In chemistry, a systematic name describes the chemical structure of a chemical substance, thus giving some information about its chemical properties.. The Compendium of Chemical Terminology published by the IUPAC defines systematic name as "a name composed wholly of specially coined or selected syllables, with or without numerical prefixes; e.g. pentane, oxazole."
The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
This systematic position of Limulus was controversial for a long time, but has been found to show that human serum is more closely related to arachnids than to crustaceans. The field of biochemistry has greatly developed since Darwin's time, and this serological study is one of the most recent pieces of evidence of evolution. A number of ...
A systematic element name is the temporary name assigned to an unknown or recently synthesized chemical element. A systematic symbol is also derived from this name. In chemistry, a transuranic element receives a permanent name and symbol only after its synthesis has been confirmed.
This list of Latin and Greek words commonly used in systematic names is intended to help those unfamiliar with classical languages to understand and remember the scientific names of organisms. The binomial nomenclature used for animals and plants is largely derived from Latin and Greek words, as are some of the names used for higher taxa , such ...
Chemical classification systems attempt to classify elements or compounds according to certain chemical functional or structural properties. Whereas the structural properties are largely intrinsic, functional properties and the derived classifications depend to a certain degree on the type of chemical interaction partners on which the function is exerted.
In chemical nomenclature, a descriptor is a notational prefix placed before the systematic substance name, which describes the configuration or the stereochemistry of the molecule. [1] Some of the listed descriptors should not be used in publications, as they no longer accurately correspond with the recommendations of the IUPAC.
