Cytoplasmic sulfur trafficking in sulfur‐oxidizing prokaryotes
IUBMB Life, 2015AbstractPersulfide 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, 1969Abstract 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, 1969Abstract 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.

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.

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.

Comments on Inorganic Chemistry, 1982
Abstract Within the last decade the number of simple, nonpolymeric sulfur oxides has tripled, and sulfur is now the element with the largest number of oxides. Excluding polymeric compounds, five binary sulfur-oxygen compounds were known in 1970: the short-lived, di-atomic sulfur monoxide (SO), the well known sulfur dioxide (SO2), two molecular forms of

Sulfur oxides comprise both gaseous and particulate chemical species. There are four of the former, namely sulfur monoxide, sulfur dioxide, sulfur trioxide and disulfur monoxide. The particulate phase sulfur oxides consist of strongly-to-weakly acidic sulfates, namely sulfuric acid (H2SO4) and its products of neutralization with ammonia: letovicite ...

Sulfur Oxides and Particulates
SAE Technical Paper Series, 1971<div class="htmlview paragraph">The effects of sulfur oxide pollution are discussed, with reference to the literature. Levels of sulfur oxide and particulates in the air are determined for different areas, and many geographic comparisons are made.

Publisher Summary This chapter discusses oxidation of sulfur (S) in soils. Soils throughout the world are increasingly recognized as being S deficient, and deficiencies in the element are even appearing in soils in countries where such deficiencies were previously unknown.
