The tri‐peptide [ 14 C]‐glutathione ([ 14 C]‐GSH) was synthesized in a single step by GSH synthetase catalyzed reaction of L ‐γ‐glutamyl‐ L ‐cysteine and [ 14 C]‐glycine. Preparative reverse phase HPLC afforded [ 14 C]‐GSH in 30% yield and 98% purity. Preparation of GSH synthetase from E. coli via recombinant DNA and the interconversion of [ 14 C]‐GSH to the disulfide [ 14 C]‐GSSG for storage are discussed. Copyright © 2010 John Wiley & Sons, Ltd.
