This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymologies. Most of them are combining forms in Neo-Latin and hence international scientific vocabulary. There are a few general rules about how they combine.
The "nor-" prefix also includes the elimination of a methylene bridge in a cyclic parent compound, followed by ring contraction. (The prefix "homo-" which indicates the next higher member in a homologous series, is usually limited to noncyclic carbons). [1] [2] [3] The terms desmethyl-or demethyl-are synonyms of "nor-". "Nor" is an abbreviation ...
Medical terminology often uses words created using prefixes and suffixes in Latin and Ancient Greek. In medicine, their meanings, and their etymology, are informed by the language of origin. Prefixes and suffixes, primarily in Greek—but also in Latin, have a droppable -o-. Medical roots generally go together according to language: Greek ...

Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Meaning: a prefix used to make words with a sense opposite to that of the root word; in this case, meaning "without" or "-less". This is usually used to describe organisms without a certain characteristic, as well as organisms in which that characteristic may not be immediately obvious.
The prefix nor-is derived as an abbreviation of the word "normal", used to indicate a demethylated compound. [5] Norepinephrine consists of a catechol moiety (a benzene ring with two adjoining hydroxyl groups in the meta - para position), and an ethylamine side chain consisting of a hydroxyl group bonded in the benzylic position.
While the use of the affix mono-is rarely necessary in organic chemistry, it is often essential in inorganic chemistry to avoid ambiguity: carbon oxide could refer to either carbon monoxide or carbon dioxide. In forming compound affixes, the numeral one is represented by the term hen-except when it forms part of the number eleven (undeca-): hence
