Research profile
Glutathione research profile
Glutathione (reduced, GSH) is the tripeptide γ-L-glutamyl-L-cysteinylglycine, the most abundant low-molecular-weight thiol in animal cells. Its γ-glutamyl bond resists ordinary peptidases, and its free thiol is oxidized to the disulfide GSSG. Hopkins named it in 1921; its structure was settled in 1929.

Frequently asked questions
What is the difference between GSH and GSSG?
GSH is reduced glutathione with a free thiol; GSSG is its oxidized disulfide dimer.
Why is the γ-glutamyl bond important?
Glutamate is linked through its side-chain carboxyl, which makes the bond resistant to ordinary peptidases.
Where do I find the certificate of analysis?
The QR code on the label opens the latest third-party certificate of analysis (COA) for this compound. You can also search the COA Portal by compound or batch number.
