WebGlutathione is a tripeptide of glutamate, cysteine, and glycine, occurring in neurons at concentrations of 0.2–2 mM; it is the most abundant low molecular weight thiol of bacteria, plant, and animal cells ( 4 – 6 ). As such, it regulates critical cellular processes such as metabolism of estrogens, prostaglandins, leukotrienes, and xenobiotic drugs. WebGlutathione (GSH) has several important functions in eukaryotic cells, and its intracellular concentration is tightly controlled. Combining mathematical models and 35 S labeling, we analyzed Saccharomyces cerevisiae sulfur metabolism. This led us to the observation that GSH recycling is markedly faster than previously estimated.
