| chemical formula | <chemistry> A represention of the elemental composition of a species, subscripts are used to indicate the relative numbers of atoms of each kind of element present. (09 Oct 1997) |
|---|---|
| chemical industry | The aggregate enterprise of manufacturing and technically producing chemicals. (12 Dec 1998) |
| chemical knife | Term sometimes used for restriction endonuclease. (05 Mar 2000) |
| chemical oxygen demand | The amount of dissolved oxygen required to combine with chemicals in wastewater. A measure of the oxygen equivalent of that portion of organic matter that is susceptible to oxidation by a strong chemical oxidizing agent. (05 Dec 1998) |
| chemical peel | A special plastic surgical procedure in which a chemical is applied to the face which removes the outer layer of the skin. This procedure is used to remove fine lines and wrinkles in the face. After a chemical peel the skin is usually very sensitive to sunlight exposure. (27 Sep 1997) |
| chemical peeling | Application of a cauterant to the skin for the purpose of causing a superficial destruction of the epidermis and upper layers of the dermis. After healing, the treated area has new epithelium. (12 Dec 1998) |
| chemical peritonitis | Peritonitis due to the escape of bile, contents of the gastrointestinal tract, or pancreatic juice into the peritoneal cavity; the contents of the fluid causes chemical injury, shock, and peritoneal exudation prior to occurrence of any associated infection. (05 Mar 2000) |
| chemical pneumonia | <chest medicine> Pneumonia caused by the inhalation of a toxic gas, such as phosgene or chlorine. (05 Jan 1998) |
| chemical potential | <chemistry> The work required (in j mol 1) to bring a molecule from a standard state (usually infinitely separated in a vacuum) to a specified concentration. More usually employed as chemical potential difference, the work required to bring one mole of a substance from a solution at one concentration to another at a different concentration, __ = RT.In (c2/cl). This definition is useful in studies of active transport, note that, for charged molecules, the electrical potential difference must also be considered (see electrochemical potential). (18 Nov 1997) |
| chemical prophylaxis | The administration of chemicals or drugs to members of a community to reduce the number of carriers of a disease and to prevent others contracting the disease. (05 Mar 2000) |
| chemical ray | A light ray toward and beyond the violet end of the spectrum that acts upon a photographic plate and produces other chemical effects. Synonym: chemical ray. (05 Mar 2000) |
| chemical reaction | <chemistry> A process in which one or more substances are changed chemically into one or more different substances. (09 Oct 1997) |
| chemical repair | Conversion of a free radical to a stable molecule. (05 Mar 2000) |
| chemical sampling | A sample that is obtained by whatever means is convenient and then purified of irrelevant elements before analysis; the assumption of thorough mixing is not necessary. (05 Mar 2000) |
| chemical sequencing | A lab technique used to determine the sequence of nucleotides in a DNA molecule. The DNA molecule is labelled with radioactive phosphorous (chemical element P), cut into fragments, and analysed through electrophoresis. (09 Oct 1997) |
