What's the difference between mercuric and paracyanogen?
Mercuric
Definition:
(a.) Of, pertaining to, or derived from, mercury; containing mercury; -- said of those compounds of mercury into which this element enters in its lowest proportion.
Example Sentences:
(1) The binding of labelled (203Hg) mercuric chloride to nuclear proteins of human peripheral blood T lymphocytes was studied by using polyacrylamide gel electrophoresis and autoradiography.
(2) Both aminopeptidases are inhibited by mercuric chloride, o-phenanthroline, dithiothreitol and 2-mercaptoethanol.
(3) Positive reactions to mercuric chloride were found in 23 (10.4%) of 222 patients.
(4) The Mob+ vector pME285 (10.6 kb) carries the aph gene and the Tn501-derived merRTCA genes coding for mercuric ion resistance, another good selective marker in Pseudomonas.
(5) A mutant of plasmid R100-1, which conferred cellular hypersensitivity to Hg2+ because of the insertion of Tn801 (TnA) into the gene determining synthesis of mercuric reductase enzyme, allowed further mutational events to be selected which resulted in either reversion to Hg2+ resistance (characteristic plasmid R100-1) or sensitivity at a level characteristic of plasmidless strains.
(6) The concentrations of mercuric acetate and phenylmercuric acetate solutions or the temperature of incubation also affected the mercury(203) uptake as well as its cellular distribution.
(7) Many strains proved resistant, at the same time, to mercuric chloride and to several antibiotics.

(11) The Bacillus MerR protein bound in vitro to its promoter-operator region in both the presence and absence of mercuric ion and functioned as a negative and positive regulator of transcription.
(12) This suggests that the isoalloxazine rings of mercuric reductase and glutathione reductase are mutually tilted in slightly different ways.
(13) The mutant lysozyme Thr 157----Cys reacts with mercuric chloride to give an excellent new derivative although Cys 157 is only approximately 60% substituted with the heavy atom.

(17) Significantly more mercury was found in rats given intraperitoneal injections compared to those intoxicated with mercuric chloride in the drinking water.
(18) Although most polynucleotides can be extensively mercurated at pH 7.0 in sodium or Trisacetate buffers, tRNA undergoes only limited substitution in Tris buffers.
(19) The patients with these reactions were also positive at a concentration of 0.05% mercuric chloride, but were negative to metallic mercury, in contrast to 2 other patients in the same group.
(20) Mercurated nucleic acid probes can be used for non-radioactive in situ hybridization.
Paracyanogen
Definition:
(n.) A polymeric modification of cyanogen, obtained as a brown or black amorphous residue by heating mercuric cyanide.
