These protein-based tools allow real-time, reversible monitoring of the glutathione redox potential (E_GSH) within living cells, offering subcellular resolution that chemical probes cannot match
Aging (Reduced Synthesis Capacity) As you age, production of glutathione declines due to: Reduced activity of gamma-glutamylcysteine ligase (GCL) , the rate-limiting enzyme in glutathione synthesis Decreased cellular energy (ATP) to fuel glutathione recycling Lower levels of precursor amino acids (especially cysteine and glycine) Studies show glutathione levels drop 10-15% per decade after age 40 [3]
