Although comparisons of abundance between different tryptic peptides are not feasible due to differences in ionization efficiencies of each peptide, these results confirm that glutathionylation of each cysteine in WT GLRX occurs following incubation with GSSG, and suggest that C23, C26, and C8 are more readily glutathionylated at lower concentrations of GSSG

The transcript shows Farah telling Usada: "So I just wanted to come clear, sorry guys, and I did take it at the time and I thought I didn't." The Usada investigator then says: "a few days before the race with Alberto present and your doctor and Barry Fudge and you're telling us all about that now but you didn't remember any of that when I kept asking you about this?"
