What's the difference between ferric and pharmacosiderite?
Ferric
Definition:
(a.) Pertaining to, derived from, or containing iron. Specifically (Chem.), denoting those compounds in which iron has a higher valence than in the ferrous compounds; as, ferric oxide; ferric acid.
Example Sentences:
(1) Thus, although ferric-enterochelin cannot penetrate the cell surface from outside, the complex that is formed within the envelope is transported normally into the cell.
(2) Ferric iron in aqueous solution was used as an iron-only control.
(3) The free radical scavengers mannitol, thiourea, benzoate, and 4-methylmercapto-2-oxobutyrate protected either native cells exposed to H2O2 or pretreated hepatocytes exposed to H2O2 and given ferric or ferrous iron.
(4) During this reaction, the complete reduction of ferric ions present in ferredoxin was observed with a fast rate under either aerobic or anaerobic conditions.
(5) The effects of naftidrofuryl have been studied on MDA production in phosphate buffer in the presence or absence of ferric ions.
(6) Iron presented as inorganic ferric or ferrous salts may also be absorbed, though the more soluble ferrous salts are adsorbed much more rapidly.
(7) By using the Lancefield method as the standard, there was 100% agreement with both the colorimetric and ferric chloride tests for hippurate hydrolysis, and 96% agreement with the CAMP test.
(8) 220 MHz proton Fourier transform (FT) NMR with quadrature phase detection (QPD) technique is applied to observe largely hyperfine-shifted signals of various hemoproteins and hemoenzymes in ferric high-spin state.
(9) An additional synthetic analog of RA, which lacks a carbonyl group at the diketopiperazine ring, exhibited the same uptake rates as ferric RA.
(10) The electronic structure of the low-spin ferric iron in cyanide complex appears to be modulated by halide binding to a protonated amino acid in the distal heme cavity.
(11) Ferric ammonium citrate, ferrous sulfate and ferrous gluconate were all found effective in preventing rat anemia when added to their drinking water.
(12) Ferric ion and ferrocyanide are bound to nodes as colloidal precipitates, and may migrate away from their sites of formation.
(13) Of several heavy metal ions, such as Fe3+, Fe2+, Co2+, Ni2+, Cu2+ and Zn2+, tested for supplementation of the alkaline growth deficiency, only iron, either added in the ferrous or ferric form, was able to restore cellular growth.
(14) Ferric reduction takes place at the plasma membrane of the root epidermis cells by a transmembrane redox system, which can be activated when iron is getting short.
(15) Ferric[59Fe] citrate was injected to rats bearing hepatoma induced by the administration of diethylnitrosamine.
(16) On the morning before a 10 d collection period, the milk-substitutes were supplemented with 59Fe as ferric chloride and 65Zn as zinc chloride.
(17) A gene (FRE1) was identified which encodes a protein required for both ferric iron reduction and efficient ferric iron assimilation, thus linking these two activities.
(18) These results, taken together, indicate a role for ferric citrate in the iron nutrition of this strain, which has been shown to be an efficient nitrogen-fixing strain on a variety of soybean cultivars.
(19) The reduced toxicity can be correlated with changes in the difference spectrum of ferric-Adriamycin vs Adriamycin (ADR), where a peak around 610 nm shifted to the 570 nm region.
(20) Electron paramagnetic resonance (EPR) at 15 K was used to probe the magnetic interaction between the visible copper CuA2+ and ferric cytochrome a in the carbon monoxide compound of beef heart cytochrome oxidase.
Pharmacosiderite
Definition:
(n.) A hydrous arsenate of iron occurring in green or yellowish green cubic crystals; cube ore.
