| hydrate crystal | One of several possible microstructural arrangements of water molecules based on intermolecular forces; suggested as being involved in the mode of action of inhalation anaesthetics. (05 Mar 2000) |

| aluminum hydrate | <chemical> Hydrated aluminum. A compound with many biomedical applications: as a gastric antacid, an antiperspirant, in dentifrices, as an emulsifier, as an adjuvant in bacterins and vaccines, in water purification, etc. Pharmacological action: antacids, pharmaceutic aid. Chemical name: Aluminum hydroxide (Al(OH)3) (12 Dec 1998) |

| amyl hydrate | C5H11NO2;a vasodilator used in angina pectoris and cyanide poisoning. (05 Mar 2000) |
| benzoyl hydrate | C6H5COOH;occurs naturally in gum benzoin; it is used as a food preservative, locally as a fungistatic, and orally as an antiseptic, diuretic, and expectorant. It is excreted rapidly as hippuric acid. Synonym: benzoyl hydrate, flowers of benzoin. (05 Mar 2000) |
| caffeine hydrate | Monohydrate of caffeine, a central nervous system stimulant. (05 Mar 2000) |
| geranyl pyrophosphate-sabinene hydrate cyclase | <enzyme> Enzyme from sweet marjoram; catalyses cation-dependent cyclization of geranyl pyrophosphate to cis and trans sabinene hydrate, deriving oh from water, not from the pyrophosphate ester Registry number: EC 5.5.- Synonym: sabinene hydrate cyclase, sabinene hydrate synthase (26 Jun 1999) |
| chloral hydrate | <chemical> A hypnotic and sedative used in the treatment of insomnia. The safety margin is too narrow for chloral hydrate to be used as a general anaesthetic in humans, but it is commonly used for that purpose in animal experiments. It is no longer considered useful as an anti-anxiety medication. Pharmacological action: sedatives, nonbarbiturate, anaesthetics, intravenous. Chemical name: 1,1-Ethanediol, 2,2,2-trichloro- (12 Dec 1998) |
| hydrate | <chemistry> A compound formed by the union of water with some other substance, generally forming a neutral body, as certain crystallized salts. A substance which does not contain water as such, but has its constituents (hydrogen, oxygen, hydroxyl) so arranged that water may be eliminated; hence, a derivative of, or compound with, hydroxyl; hydroxide; as, ethyl hydrate, or common alcohol; calcium hydrate, or slaked lime. Origin: Gr. "ydwr water: cf. F. Hydrate. Source: Websters Dictionary (01 Mar 1998) |
| hydrate microcrystal theory of anaesthesia | A theory of narcosis pertaining to nonhydrogen-bonding agents; postulates the interaction of the molecules of the anaesthetic drug with water molecules in the brain. Synonym: Pauling's theory. (05 Mar 2000) |
| triketohydrindene hydrate | Former name for ninhydrin. (05 Mar 2000) |
| folliculin hydrate | <chemical> (16 alpha,17 beta)-estra-1,3,5(10)-triene-3,16,17-triol. A metabolite of estradiol and usually the predominant oestrogenic metabolite in urine. During pregnancy, large amounts of estriol are produced by the placenta. It has also been obtained from plant sources. The 16 beta-isomer has also been isolated from the urine of pregnant women. Chemical name: Estra-1,3,5(10)-triene-3,16,17-triol, (16alpha,17beta)- (12 Dec 1998) |
| chiral crystal | An enantiomorphic, dyssymmetric, optically active crystal. (05 Mar 2000) |
| phase, crystal | <microscopy> A specific crystal structure, usually given a name. (05 Aug 1998) |
| clathrate crystal | Lattice-like arrangement of molecules of one substance surrounding molecules of another substance. (05 Mar 2000) |
| crystal | A solid of regular shape and, for a given compound, characteristic angles, formed when an element or compound solidifies slowly enough, as a result either of freezing from the liquid form or of precipitating out of solution, to allow the individual molecules to take up regular positions with respect to one another. Origin: G. Krystallos, clear ice, crystal (05 Mar 2000) |
| crystal, birefringent | <microscopy> A crystalline substance which is anisotropic with respect to the velocity of light. (05 Aug 1998) |
