After absorption, the first step of the reductive assimilation of sulfate is its adenylation to adenosine 5-phosphosulfate (APS), a reaction catalyzed by ATP sulfurylases (ATPS) (Figure 1

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]

Recent studies have successfully linked gene mutations to transcriptional phenotypes through CRISPR screening and single-cell transcriptomics via Perturb-seq methods
