Effects of sulfur oxides on eicosanoids

Journal of Toxicology and Environmental Health, 1989
Ultrafine metal oxides and SO2 react during coal combustion or smelting operations to form primary emissions coated with an acidic SOx layer. Ongoing work in this laboratory has examined the effects of sulfur oxides on pulmonary functions of guinea pigs.

Inorganic sulfur oxidizing system in green sulfur bacteria

Photosynthesis Research, 2010
Green sulfur bacteria use various reduced sulfur compounds such as sulfide, elemental sulfur, and thiosulfate as electron donors for photoautotrophic growth. This article briefly summarizes what is known about the inorganic sulfur oxidizing systems of these bacteria with emphasis on the biochemical aspects.

Cytoplasmic sulfur trafficking in sulfur‐oxidizing prokaryotes

IUBMB Life, 2015
AbstractPersulfide groups are chemically versatile and participate in a wide array of biochemical pathways. Although it is well documented that persulfurated proteins supply a number of important and elaborate biosynthetic pathways with sulfane sulfur, it is far less acknowledged that the enzymatic generation of persulfidic sulfur, the successive ...

The stereochemistry of oxidation at sulfur

Tetrahedron, 1969
Abstract Oxidation of 2-thiabicyclo[2.2.1]heptane by a variety of oxidizing agents provided both endo and exo sulfoxides. The ratio of these sulfoxide isomers is a function of the relative stability of the sulfoxides and/or the mechanism of the oxidation reaction.

Oxidation of sulfur hexafluoride

Journal of Inorganic and Nuclear Chemistry, 1969
Abstract Although SF 6 is extraordinarily inert toward oxygen, reaction can be initiated by the electrical explosion of extremely small masses of platinum into SF 6 O 2 mixtures. It is shown that chemically trivial amounts of exploding metal can be effective initiators of the SF 6 oxidation.

Toxicology of Sulfur Oxides

1999
Publisher Summary This chapter describes the effect of sulfur dioxide (SO 2 ) on health. The toxicologically significant sulfur oxides are the gaseous SO 2 , produced primarily from combustion sources, and sulfuric acid and ammonium bisulfate, the secondarily derived particulate strongly acidic sulfates.

3.5.2 Oxidation at Sulfur

2015
AbstractThe asymmetric biocatalytic oxidation of sulfides can be performed with high enantioselectivity by a number of different enzymes, allowing access to biologically active compounds including flavors and pharmaceuticals, and also chiral auxiliaries for organic synthesis.
