Its two-step synthesis glutamate-cysteine ligase (GCL, rate-limiting, producing -glutamylcysteine at the cost of one ATP) followed by glutathione synthetase (adding glycine, consuming a second ATP) produces a tripeptide whose unusual -glutamyl linkage between glutamate's -carboxylate and cysteine's amine renders it resistant to cellular peptidases, enabling accumulation to 0.515 mM concentrations in most cell types

The study highlights correlations between therapy response and specific alleles based on a robust biologic or clinical effect
