Sulfur Dioxide and its role in Winemaking | Terlato Wines ...

Sulfur Dioxide (SO2) is the most common chemical compound used in winemaking. Its preservative and anti-bacterial qualities were discovered thousands of years ago, and because it is non-toxic it has been used in foods and wine since antiquity.Sulfur is naturally present on the grape skins, and though it is typically not enough for ensure against spoilage for winemaking purposes, it means that ...

Sulfur dioxide | SO2 - PubChem

Sulfur dioxide (SO2) can be produced endogenously from normal metabolism of sulfur-containing amino acids. L-cysteine is oxidized via cysteine dioxygenase to L-cysteinesulfinate, and the latter can proceed through transamination by glutamate oxaloacetate transaminase (GOT) to beta-sulfinylpyruvate which decomposes spontaneously to pyruvate and ...

Sulfur Dioxide (SO CAS ; UN 1079

Sulfur dioxide dissolves in water or steam to form sulfurous acid. Liquid sulfur dioxide corrodes iron, brass, copper, and some forms of plastic and rubber. Many metals, including zinc, aluminum, cesium, and iron, incandesce and/or ignite in unheated sulfur dioxide. Sulfur dioxide reacts explosively when it comes in contact with sodium hydride.
