2019), or to support regeneration of GSH oxidized by other compounds such as superoxide (Polle 2001), as well as some of the thiol peroxidases discussed further below
Further mechanistic investigations determined that the elevation of intracellular GSSG levels resulted in NF-B inhibition by facilitating glutathionylated IKK- (IKK--SSG) formation, leading to enhanced TNF hepatotoxicity
While in vitro equilibrations between redox couples such as roGFP2 and GSH/GSSG require minutes or even hours to reach a thermodynamic endpoint (G = 0), enzyme-catalyzed thiol-disulfide exchange reactions usually occur very rapidly and either maintain or reach a steady state (G 0) 7,31,32,60,63,67,78,79
One downside is that the cost per soap is on the higher side
