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 ...

American Journal of Health-System Pharmacy, 1985
The occurrence of sulfites in foods, drug products, and the environment; the characteristics of sulfite-sensitivity reactions; and the management of sulfite-sensitive individuals are reviewed. Sulfites are used in foods, beverages, and pharmaceuticals for their antioxidant properties; they are frequently used in restaurant foods to keep vegetables and ...

[Reflections on the sulfite test in sulfite intolerance].
Allergie et immunologie, 1988Detection of sulphite sensitivity can be simplified by use of sulphite test. However, because of the precautions and limitations it is difficult to suggest its use for all patients.

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.

Inhibition of Browning by Sulfites
1991The present state of understanding of the mechanisms by which sulfites inhibit browning reactions in food is reviewed. The difficulties of specifying the composition of sulfur(IV) oxospecies in sulfited foods arise from the existence of labile equilibria between SO2, HSO3-, SO3(2-) and S2O5(2-), whose position depends on concentration, ionic strength ...

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.

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 ...

Sulfite-treated lettuce challenges in sulfite-sensitive subjects with asthma
Journal of Allergy and Clinical Immunology, 1989This study was designed to determine whether lettuce treated with a commercially available sulfite-containing freshener prepared according to manufacturer's directions could provoke reactions in sulfite-sensitive subjects with asthma (SSAs). Five adult SSAs with stable asthma who had multiple prior reactions to double-blind, placebo-controlled, sulfite-

Isolation of sulfited oligosaccharides from glycoproteins treated with alkaline sulfite
Carbohydrate Research, 1984The oligosaccharide products resulting from treatment of mucin-type glycoproteins with alkali in the presence of the sulfite anion have been investigated. Treatment of fetuin and of tryptic glycopeptides from the human erythrocyte with this reagent resulted in the release of sulfited oligosaccharides identified as N-acetylsulfohexosamine (HexNAcSO3 ...

Traveling Waves in the Iodate-Sulfite and Bromate-Sulfite Systems
The Journal of Physical Chemistry, 1995We investigated traveling fronts of the oxidation of sulfite by iodate and by bromate. Isothermal density changes (A@,) and enthalpies were determined, the latter being negative in both cases. The Ae, is negative in the iodate-sulfite system but positive in the bromate-sulfite system.
