| trivial name | A name of a chemical, no part of which is necessarily used in a systematic sense; i.e., it gives little or no indication as to chemical structure. Such names are common for drugs, hormones, proteins, and other biologicals, and are used by the general public. They may not be officially sanctioned, in contrast to nonproprietary names, but may be adopted as official nonproprietary names as a result of widespread usage. Examples are water, aspirin, chlorophyll, haem, methotrexate, folic acid, caffeine, thyroxine, epinephrine, barbital, etc.; also common abbreviations for chemically defined substances, such as ACTH, MSH, BAL, DDT, which are spoken as such and not in terms of the words they represent. The distinction between trivial and semitrivial names is seldom made; thus tetrahydrofolate, methylglycine, glucosamine, etc., are often termed trivial even though each contains a systematic part that is used in the correct systematic sense (tetrahydro for four hydrogen atoms, methyl for a -CH3 group, amine for -NH2 in the above). Trivial names are often assigned arbitrarily to chemical compounds, especially from natural sources, before the chemical structures, hence systematic names can be assigned; also, they afford useful shortenings of long systematic names even when these can be stated (although most such shortenings turn out to be semisystematic, as they incorporate some portion of the systematic name).

| activation product | <radiobiology> The unstable nucleus formed when activation occurs. (See activation above.) (09 Oct 1997) |
| by-product | <chemistry> A product of a chemical reaction or industrial process which is different from the desired product. (20 Mar 1998) |
| by-product material | Radioactive material produced by nuclear fission or by neutron irradiation in a nuclear reactor or similar device. (05 Mar 2000) |
| gene product | The biochemical material, either RNA or protein, resulting from expression of a gene. The amount of gene product is used to measure how active a gene is, abnormal amounts can be correlated with disease-causing alleles. (09 Oct 1997) |
| cleavage product | A substance resulting from the splitting of a molecule into two or more simpler molecules. (05 Mar 2000) |
| product | 1. Anything that is produced, whether as the result of generation, growth, labour, or thought, or by the operation of involuntary causes; as, the products of the season, or of the farm; the products of manufactures; the products of the brain. "There are the product Of those ill-mated marriages." (Milton) "These institutions are the products of enthusiasm." (Burke) 2. <mathematics> The number or sum obtained by adding one number or quantity to itself as many times as there are units in another number; the number resulting from the multiplication of two or more numbers; as, the product of the multiplication of 7 by 5 is 35. In general, the result of any kind of multiplication. See the Note under Multiplication. Synonym: Produce, production, fruit, result, effect, consequence, outcome, work, performance. Origin: L. Productus, p. Pr. Of producere. See Produce. Source: Websters Dictionary (01 Mar 1998) |
| product, gene | The RNA or protein that results from the expression of a gene. The amount of gene product is a measure of the degree of gene activity. (12 Dec 1998) |
| product inhibition | Inhibition of an enzyme activity by a product of the reaction catalyzed by that enzyme. (05 Mar 2000) |
| product labeling | Use of written, printed, or graphic materials upon or accompanying a product or its container or wrapper. It includes purpose, effect, description, directions, hazards, warnings, and other relevant information. (12 Dec 1998) |
| product line management | Management control systems for structuring health care delivery strategies around case types, as in drgs, or specific clinical services. (12 Dec 1998) |
| product-moment correlation | A statistical procedure which yields the correlation coefficient referred to as r (-1.00 to +1.00) and involves the actual values, rather than the ranks (rank order) of the measurements. (05 Mar 2000) |
| product packaging | Form in which product is processed or wrapped and labelled. (12 Dec 1998) |
| product recovery | The process of separating a desired recombinant protein from the growth medium and the other elements in the host cells in which it was grown. (14 Nov 1997) |
| product surveillance, postmarketing | Surveillance of drugs, devices, appliances, etc., for efficacy or adverse effects, after they have been released for general sale. (12 Dec 1998) |
