Notice that in the oxidized (disulfide) state, each sulfur atom has lost a bond to hydrogen and gained a bond to a sulfur - this is why the disulfide state is considered to be oxidized relative to the thiol state. These reducing agents function in a manner similar to that of GSH, except that DTT, because it has two thiol groups, forms an intramolecular disulfide in its oxidized form. [1], Sodium sulfite can be prepared by treating a solution of sodium hydroxide with sulfur dioxide. It is used as a reagent in sulfonation and sulfomethylation agent. Another main reason behind the solubility of sodium sulfide in water is, it is an ionic compound that tends to disassociate its ions in water.
