Abstract
Sulfane sulfur is a reactive, divalent sulfur atom bonded to another sulfur. It modifies cysteine residues in proteins and thus changes enzyme activities.
Also, it may be bound to glutathione and this greatly increases its antioxidative properties. Analytical methods used for the determination of sulfane sulfur are discussed and our developed method using an extractive alkylation technique is mentioned.
The sulfane sulfur donor compounds are described and categorized. The potential use and future perspectives of this monoelemental antioxidant are summarised and discussed.
