Gsh reactivity

Webdatapoints in the absence of GSH. Thiol reactivity was assessed by measuring fragment depletion with a large excess of GSH12 that provided the rate constant k deg+GSH as the sum of the thiol-reactivity and the degradation. The GSH reactivity of the electrophile was then calculated from these two rate constants as k GSH = k deg+GSH − k deg ... WebJul 15, 2024 · It is worth noting that not all cysteine reactivity studies contain methyl-thiolate as a probe, and GSH is not used exclusively in reactivity assays .
