Contact Dermatitis, 1994
In the last 2 years, 2,894 consecutive eczematous patients were patch tested with sodium metabisulfite 1% pet. Positive reactions were elicited in 50 subjects (1.7%). All 50 patients were also positive to potassium metabisulfite 1% pet. and sodium bisulfite 1% and 5% pet., while only 2 of them were positive to sodium sulfite 1% pet.

Sulfite-oxidizing enzymes (SOEs) are molybdenum enzymes that exist in almost all forms of life where they carry out important functions in protecting cells and organisms against sulfite-induced damage. Due to their nearly ubiquitous presence in living cells, these enzymes can be assumed to be evolutionarily ancient, and this is reflected in the fact ...

Triaquamanganese sulfite revisited
Acta Crystallographica Section C Crystal Structure Communications, 2006Orthorhombic Mn(SO3)(H2O)3 has been reinvestigated by single-crystal X-ray diffraction in two possible space groups, viz. P2(1)2(1)2(1) (with all atoms in general positions) and Pnma (with the molecule bisected by a mirror plane). The results confirm the lower symmetry assigned in a previous single-crystal neutron diffraction study.

Sulfite sensitivity and sulfite oxidase actiivty inDrosophila melanogaster
Biochemical Genetics, 1993The relationship between sulfite oxidase (SO) and sulfite sensitivity in Drosophila melanogaster is addressed. Significant improvements to the SO assay have provided an investigative tool which can be applied to further studies of this molybdoenzyme. Using the second-instar larval stage of D, melanogaster, we have shown a direct relationship between ...

Sulfite determination: Sulfite oxidase
1987Publisher Summary This chapter discusses the sulfite determination. Sulfite and sulfite adducts—for example, aldehyde-bisulfite addition compounds—are distributed in very low concentrations in plants and animals. Their physiological importance is unknown.

Despite its reactivity and hence toxicity to living cells, sulfite is readily converted by various microorganisms using distinct assimilatory and dissimilatory metabolic routes. In respiratory pathways, sulfite either serves as a primary electron donor or terminal electron acceptor (yielding sulfate or sulfide, respectively), and its conversion drives ...

JAMA: The Journal of the American Medical Association, 1984
Sulfiting agents, including sulfur dioxide, potassium metabisulfite, sodium sulfite, sodium metabisulfite, sodium bisulfite, and potassium bisulfite, are effective antioxidants. As such they are used widely as additives in processed beverages and foods, including fruit juices, soft drinks, wines, beers, cider, vinegar, potato chips, dried fruits, and ...
