What's the difference between halogen and halogenous?
Halogen
Definition:
(n.) An electro-negative element or radical, which, by combination with a metal, forms a haloid salt; especially, chlorine, bromine, and iodine; sometimes, also, fluorine and cyanogen. See Chlorine family, under Chlorine.
Example Sentences:
(1) 5-Bromo-5'-amino-2',5'-dideoxyuridine (11, ABrU) and 5-iodo-5'-amino-2',5'-dideoxyuridine (12, AIU) were prepared by halogenation of the 5-mercuriacetate of 5'-amino-2',5'-dideoxyuridine.
(2) Such disturbances may be induced by opiates, benzodiazepines, phenothiazines, butyrophenones, ketamine, etomidate, propofol, nitrous oxide, and halogenated inhalation anesthetics as well as by H2-blocking agents such as cimetidine.
(3) It is concluded that both halogenated and natural purine ribonucleotides interact in a similar manner with the enzyme molecule.
(4) The flumazenil analogue, Ro 16-0154, a benzodiazepine partial inverse agonist, has been labeled by halogen exchange to enable SPECT investigations of central benzodiazepine receptors in the human brain.
(5) The estrogen receptor seems to have a moderate tolerance for bulky substituents: All of the halogen and halomethyl substituents bind with an affinity at least 50% that of estradiol; in the three atom alkyl series, the affinity declined markedly from propargyl (44%) and allyl (38%) to propyl (5%), suggestive of detailed steric constraints or a preference for unsaturation.
(6) Annual savings in tonnes of CO 2 Install 2 kilowatt solar PV panels 0.4 Buy a new A++ refrigerator if yours is more than 4 years old, and only use a small-screen TV 0.1 Use LED or fluorescent lights where you currently have halogen lights installed 0.1 Buy an automated system to turn off appliances when not in use; get a meter that shows actual energy use and use it to monitor your household 0.1 Only use your washing machine and dishwasher when full to capacity and at lowest temperature 0.1 Never use the tumble dryer 0.1 Get rid of the freezer if you can, and replace your small appliances with "eco" varieties 0.1 Car (1.5 tonnes of CO 2 ) There is one car for every two people in the UK, and each one travels an average of about 9,000 miles a year.
(7) We have studied the time-resolved and the steady-state fluorescence of the DNA groove binders 4',6-diamidino-2-phenylindole (DAPI) and Hoechst 33258 with the double stranded DNAs poly(dA-dU) and poly(dI-dC) and their halogenated analogs, poly(dA-I5dU) and poly(dI-Br5dC).
(8) Halogenated anthelmintics were not metabolized to GSH conjugates in the helminths studied and did not inhibit GSH-S-aryltransferase activity towards chlorodinitrobenzene.
(9) Replacement of the 6-Cl group of amiloride by other halogen atoms had only modest effects on drug efficacy.
(10) This cannot be explained by metabolic activation of the halogenated hydrocarbons but could be due to a noxious effect on the mitotoc spindle.
(11) These observations indicate that Compound X is the halogenating intermediate in the chlorite reaction and that the rate of enzymatic chlorination is directly related to the stability of Compound X.
(12) As radiation sources, the following ones have proved useful: high-pressure mercury-vapour lamps, compound radiation systems consisting of high-pressure mercury-vapour burner, series coiled filament and reflector bulbs made of special glass as well as halogen metal-vapour lamps.
(13) This result suggests that a benefit may be expected in the clinic from the combined application of halogenated pyrimidines with repair inhibitors, if administered at a carefully screened range of concentrations.
(14) GC detection was carried out with a Coulson conductivity detector in the halogen (reductive) mode.
(15) Glutaraldehyde might inhibit Cl- transport in the TAL by cross-linking amino acid residues of the proteins essential for halogen transport across this segment.
(16) Treatment was administered with white light produced by a commercially available halogen-tungsten lamp.
(17) Various organic substances, which were measured by different indices such as total trihalomethanes (THM), total organic halogen (TOX) and the absorbence at 260 nm, could be recovered by this method much more efficiently and conveniently than by conventional methods.
(18) These results indicate that B cell mitogens act to release virus by a mechanism that differs from that of halogenated pyrimidines.
(19) Stability of halogenated volatile anesthetic is important because of the potential toxicity associated with the breakdown products.
(20) 111 chemicals of known rodent carcinogenicity (49 carcinogens, 62 noncarcinogens), including many promoters of carcinogenesis, nongenotoxic carcinogens, hepatocarcinogens, and halogenated hydrocarbons, were selected for study.
