What's the difference between cupreous and cupric?
Cupreous
Definition:
(a.) Consisting of copper or resembling copper; coppery.
Example Sentences:
(1) The enzyme activation by cupreous ions is countered by the enzyme inhibition by cupric ions, the rate of inhibition being determined by the level of cupric ions.
Cupric
Definition:
(a.) Of, pertaining to, or derived from, copper; containing copper; -- said of those compounds of copper in which this element is present in its lowest proportion.
Example Sentences:
(1) The chemistry involved reaction rate constant measurements of MSF hydrolysis and for reactions with phenolic, amine, oxime, hydroxamic acid, phenyl N-hydroxycarbamate, and hydroxylamine compounds and cupric imidazole and bipyridyl complexes.
(2) Sulfate, with or without choline, had little effect in the presence of cupric sulfate.
(3) Its unexpectedly low value is interpreted that MSF does not possess a site with sufficient basicity to be protonated by strong acid, to enter into hydrogen bonding, or for coordination with the cupric ion.
(4) However, variations in cupric ion activity rather than pH per se could explain these effects.
(5) Saponin-permeabilized polymorphonuclear leukocytes (PMNs) released beta-glucuronidase, a lysosomal enzyme, dose-dependently in response to cupric phenanthroline (CuPh), a mild oxidant, which catalyzes the formation of disulfide bridges.
(6) Several copper and cupric ion sources were shown to kill or inhibit the growth of Neisseria gonorrhoeae in vitro.
(7) When these irradiated preparations are exposed to ferrous or cupric salts a further fragmentation of monoamine oxidase ensues, especially at acid pH.
(8) Condensation of the glyoxal obtained by cupric acetate oxidation of 21-hydroxycorticosteroids with acetous phenylhydrazine reagent affords a near UV chromophore.
(9) Intraperitoneal injections of cupric acetate increased serum levels of cholesterol and phospholipids without liver damage.
(10) It is suggested that cupric ions, at high concentrations, have an inhibiting effect on myometrial activity.
(11) The products formed were separated by chromatography on the paper; then they were stained with ninhydrin and converted into cupric complexes during extraction with ethanol; the optic density was measured at 510 nm.
(12) Under the conditions of this study, it is possible that cuprous ion would be oxidised to the cupric form generating free radicals in the process.
(13) These results suggest that the enzyme may have two essential carboxyl groups at the active site, one reactive with DAN in the presence of cupric ions and the other with EPNP, and that pepstatin binds part of the active site to inhibit the reactions with DAN and EPNP as well as the enzyme activity.
(14) The inhibition of xanthine oxidase by quercetin was not affected by cupric ion.
(15) Diagnostic potentialities of the crystallo-optic++ analysis of cupric chloride crystallographs++ were studied in 76 children with pyelonephritis and in 50 children with glomerulonephritis.
(16) Biotinylated DNA or RNA is used as a hybridization probe in solution, avidin is then added to label both the probe and hybrid molecules, and the hybridization mixture chromatographed over cupric-iminodiacetic acid agarose beads.
(17) Zinc, cupric, and cadmium ions, in that order of effectiveness, inhibited lysis of washed, rabbit erythrocytes by the toxic bacterial product aerolysin.
(18) Oxidative cyclization of 2',3'-O-isopropylideneadenosines to the corresponding 5'-O,8-cyclo-2',3'-O-isopropylideneadenosines was achieved by using by lead tetraacetate, cupric chloride, and N-halogeno-succinimide as an oxidant, and by irradiation with a uv-visible light in the presence of pyrimido[5,4-g]pteridinetetrone 5-oxide.
(19) The predominant site of interaction of cupric ion was the unsubstituted nitrogen atom (N-3) on the metronidazole molecule.
(20) Previously described false-negative results with vitamin C, bile, and certain antacids were confirmed, as were false-positive results with iodide, bromide, cupric sulfate, iron salts, and hypochlorite.
