Sulfonamide allergy and sulfites asthma


Not to be confused with, sulfur trioxide. Sulfites or sulphites are compounds that contain the sulfite ion (or the sulfate(IV) ion, from its correct systematic name SO2.

The sulfite ion is the conjugate base of bisulfite. Although its acid ( sulfurous acid ) is elusive, 1 its salts are widely used.

Sulfites are substances that naturally medicine occur in some foods and the human body. They are also used as regulated food additives. Structure edit, the structure of the sulfite anion.

The structure of the sulfite anion can be described with three equivalent resonance structures. In each resonance structure, the sulfur atom is double-bonded to one oxygen allergy atom with a formal charge of zero (neutral and sulfur is singly bonded to the other two oxygen atoms, which each carry a formal charge of 1, together accounting for the 2 charge. There is also a non-bonded lone pair on the sulfur, so the structure predicted.

Vsepr theory is trigonal pyramidal, as in ammonia (NH3). In the hybrid resonance structure, the S-O bonds are equivalently of bond order one and one-third. Evidence from 17O, nMR spectroscopic data suggests that protonation of the sulfite ion gives a mixture of isomers: 1, commercial uses edit, sulfites are used as a food preservative or enhancer.

They may come in various forms, such as: 3 Wine edit Sulfites occur naturally in all wines to some extent. 4 Sulfites are commonly introduced to arrest fermentation at a desired time, and may also be added to wine as preservatives to prevent spoilage and oxidation at several stages of the winemaking.

Sulfur dioxide (SO2) protects wine from not only oxidation, but also from bacteria. Without sulfites, grape juice would quickly turn to vinegar. 5 Organic wines are not necessarily sulfite-free, but generally have lower amounts and regulations stipulate lower maximum sulfite contents for these wines.

In general, white wines contain more sulfites than red wines and sweeter wines contain more sulfites than drier ones. 6 In the United States, wines bottled after mid-1987 must have a label stating that they contain sulfites if they contain more than 10 parts per million.
