| 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) |
| vertical | 1. Of or pertaining to the vertex; situated at the vertex, or highest point; directly overhead, or in the zenith; perpendicularly above one. "Charity . . . Is the vertical top of all religion." (Jer. Taylor) 2. Perpendicular to the plane of the horizon; upright; plumb; as, a vertical line. <astronomy> Vertical angle, an angle measured on a vertical circle, called an angle of elevation, or altitude, when reckoned from the horizon upward, and of depression when downward below the horizon. <botany> Vertical anthers The plane passing through the point of sight, and perpendicular to the ground plane, and also to the picture. Vertical sash, a sash sliding up and down. Cf. French sash, under 3d Sash. Vertical steam engine, a steam engine having the crank shaft vertically above or below a vertical cylinder. Origin: Cf. F. Vertical. See Vertex. 1. Vertical position; zenith. 2. <mathematics> A vertical line, plane, or circle. Prime vertical, Prime vertical dial. See Prime. Source: Websters Dictionary (01 Mar 1998) |
| vertical axis | In dentistry, the line around which the working side condyle rotates in the horizontal plane during mandibular movement. (05 Mar 2000) |
| vertical classification | <zoology> Classification which stresses common descent and tends to unite ancestral and descendant groups of a phyletic line in a single higher taxon, separating them from contemporaneous taxa having reached a similar grade of evolutionary change. Compare: Horizontal classification. (09 Jan 1998) |
| vertical dimension | The length of the face determined by the distance of separation of jaws. Occlusal vertical dimension (ovd or vdo) or contact vertical dimension is the lower face height with the teeth in centric occlusion. Rest vertical dimension (vdr) is the lower face height measured from a chin point to a point just below the nose, with the mandible in rest position. (12 Dec 1998) |
| vertical displacement event | Disruption which occurs because plasma is not adequately stabilised against vertical motions. (09 Oct 1997) |
| vertical elastic | Elastic material used in a direction perpendicular to the occlusal plane, connecting one arch wire to the other, and usually used to improve intercuspation. (05 Mar 2000) |
