| aldol condensation | Formation of an aldol (a beta-hydroxy carbonyl compound) from two carbonyl compounds; the reverse reaction is an aldol cleavage; fructose 1,6-bisphosphate aldolase catalyses such a reaction. (05 Mar 2000) |
|---|---|
| beta-oxidation-condensation theory | <biochemistry> That the two carbon fragments split from the fatty acid molecule by beta-oxidation are converted to acetic acid and then condensed to acetoacetic acid. (05 Mar 2000) |
| chromosome condensation | <cell biology> The tight packing of DNA into chromosomes in metaphase, in preparation for cell division. (18 Nov 1997) |
| Claisen condensation | The formation of a beta-keto ester from two esters, one of which has an alpha-hydrogen atom; malate synthase, citrate synthase, and ATP citrate lyase all catalyze such reactions. (05 Mar 2000) |
| condensation | <chemistry> The process whereby a gas becomes a liquid or a solid. A chemical reaction between two organic compounds which produces (among other things) water, ammonia, or a simple alcohol. A chemical reaction between two molecules which links them together and expels a molecule of water. For example: the joining of two amino acids by a peptide bond during the formation of a polypeptide. (05 Jan 1998) |
| condensation compound | A compound resulting from the combination of two or more simple substances, with the splitting off of some other substance, such as alcohol or water; e.g., a peptide. Compare: conjugated compound. (05 Mar 2000) |
| condensation polymer | <chemistry> The kind of polymer that is formed by the combination of monomers and the release of a small molecules at the point where monomers are joined. (05 Jan 1998) |
| dehydration-condensation reaction | The joining of two molecules to each other with the release of a water molecule in the process. Compare: hydrolysis. (09 Oct 1997) |
| fractional condensation | A lab technique used to separate the components of a vapor containing a mixture of substances. This is done by taking advantage of the fact that the different chemicals have different boiling points. The mixture undergoes repeated condensations, where the chemical with the highest boiling point condenses out of the vapor first and can be separated from the rest, then the chemical with the next highest boiling point condenses out, etc. (09 Oct 1997) |
| active principle | A constituent of a drug, usually an alkaloid or glycoside, upon the presence of which the characteristic therapeutic action of the substance largely depends. (05 Mar 2000) |
| antianaemic principle | The material in liver (and certain other tissues) that stimulates haemopoiesis in pernicious anaemia; for practical purposes, the antianaemic effect of extracts from such tissues is approximately equivalent to the content of vitamin B12. (05 Mar 2000) |
| azygos vein principle | A principle based on the observation that animals can survive prolonged vena caval occlusion without sequelae: if blood from the azygos vein alone is permitted to enter the heart, patients are perfused during cardiac and pulmonary bypass at flows much less than the normal resting cardiac output. Synonym: low flow principle. (05 Mar 2000) |
| Bernoulli's principle | <physics> When friction is negligible, the velocity of flow of a gas or fluid through a tube is inversely related to its pressure against the side of the tube; i.e., velocity is greatest and pressure lowest at a point of constriction. Synonym: Bernoulli's principle, Bernoulli's theorem. (05 Mar 2000) |
| pain-pleasure principle | A psychoanalytic concept that, in a human's psychic functioning, he/she tends to seek pleasure and avoid pain; a term borrowed by experimental psychology to denote the same tendency of an animal in a learning situation. Synonym: pleasure principle. (05 Mar 2000) |
| reality principle | The concept that the pleasure principle in personality development is modified by the demands of external reality; the principle or force that compels the growing child to adapt to the demands of external reality. (05 Mar 2000) |
