How is tetrathionate produced?
5B); specifically, tetrathionate is produced when inflammatory oxygen radicals react with thiosulphate derived from the hydrogen sulphide produced by fermentative gut commensals (Winter & Baumler, 2011).
What is thiosulfate oxidised to?
sulfate
Under neutral or slightly acidic growth conditions thiosulfate dehydrogenase (TsdA) catalyzes some of the thiosulfate to tetrathionate, while thiosulfate oxidizes to sulfate with the formation of sulfur globules through the Sox system.
What is branched thiosulfate oxidation pathway?
The branched thiosulfate oxidation pathway, a mechanism in which water-insoluble globules of intermediate sulfur are formed during the oxidation of thiosulfate and sulfide.
What’s the chemical formula of sodium tetrathionate?
Sodium tetrathionate is a salt of sodium and tetrathionate with the formula Na2S4O6xH2O. The salt normally is obtained as the dihydrate (x = 2). It is a colorless, water-soluble solid….Sodium tetrathionate.

What is tetrathionate reductase?
Part of a membrane-bound tetrathionate reductase that catalyzes the reduction of tetrathionate to thiosulfate. TtrA is the catalytic subunit. During mice infection, the ability to use tetrathionate as an electron acceptor is a growth advantage for S.
What is the structure of Tetrathionate ion?
How is thiosulfate formed?
Formation. Thiosulfate is produced by the reaction of sulfite ion with elemental sulfur, and by incomplete oxidation of sulfides (pyrite oxidation), sodium thiosulfate can be formed by disproportionation of sulfur dissolving in sodium hydroxide (similar to phosphorus).
What is the process of sulfur cycle?
The sulfur cycle describes the movement of sulfur through the geosphere and biosphere. Sulfur is released from rocks through weathering, and then assimilated by microbes and plants. It is then passed up the food chain and assimilated by plants and animals, and released when they decompose.
How is sodium thiosulfate formed?
What is the total number of valence electrons in the tetrathionate ion?
Question: The total number of valence electrons in the tetrathionate ion, S4062-, is 56.
How is tetrathionate oxidized to thiosulfate in bacteria?
The production of tetrathionate is likely coupled with enzymes that subsequently split tetrathionate to thiosulfate, sulfate, or elemental sulfur [ 25, 26 ]. In addition, the Betaproteobacteria Advenella kashmirensis either oxidizes tetrathionate to sulfate or uses it as an intermediate during thiosulfate oxidation [ 27 ].
How to describe the structure of a tetrathionate?
Structure. Tetrathionate’s structure can be visualized by following three edges of a cube, as in the diagram below. The structure shown is the configuration of S 4O2− 6 in BaS 4 O 6 ·2H 2 O and Na 2 S 4 O 6 ·2H 2 O. Dihedral S–S–S–S angles approaching 90° are common in polysulfides .
What is the oxidation state of a tetrathionate anion?
The tetrathionate anion, S 4O2− 6, is a sulfur oxoanion derived from the compound tetrathionic acid, H 2 S 4 O 6. Two of the sulfur atoms present in the ion are in oxidation state 0 and two are in oxidation state +5. Alternatively, the compound can be viewed as the adduct resulting from the binding of S2− 2 to SO3.
What kind of corrosion is caused by tetrathionate?
As other species of sulfur at intermediate oxidation state, such as thiosulfate, tetrathionate can be responsible for the pitting corrosion of carbon steel and stainless steel .
