Figure 1From: Fundamental roles of reactive oxygen species and protective mechanisms in the female reproductive systemReaction of sulfhydryl group in response to oxidative stress and interconversion among the oxidation products. Sulfhydryl residues form different oxidative states that largely depends on the source and extent of oxidative stress. Since the redox system generally relies on reactive sulfhydryls, whether they are reversible or not is of prime importance.Back to article page
