The two cysteines in this motif catalyze glutathione (GSH)-dependent thiol-disulfide exchange reactions, i.e., the reduction of protein disulfides and, with high specificity, reversible (de-)glutathionylation [19] Oxidized Grxs are reduced by GSH, the resulting GSH disulfide (GSSG) by glutathione reductase (GR) using NADPH as electron source [20]

The peptide did not force sedation

In addition, Cu2+ triggered the Fenton reaction to generate ROS, and SF consumed GSH in cells, thus promoting redox stress and amplifying the effect of Cu2+
