Glutathione (穀胱甘肽)
GSH is the reduced form of glutathione. GSSG is the oxidized form of glutathione.
GSH是 還原型 的 穀胱甘肽。GSSG是 氧化型 的 穀胱甘肽。

Glutathione is an important tripeptide present in significant concentrations in all tissues. It contains glutamic acid, cysteine, and glycine. What is unusual about the structure of glutathione (bottom figure in the left graphic; Compare it to a "normal" tripeptide of glu-cys-gly (top graphic).

Instead of the usual backbone, the carboxyl acid "side chain" is part of the backbone peptide structure. The normal carboxyl group is the so called side chain in this case.

The function of glutathione is to protect cells from oxidizing agents which might otherwise damage them. The oxidizing agents react with the -SH group of cysteine of the glutathione instead of doing damage elsewhere. Many foreign chemicals get attached to glutathione, which is really acting as a detoxifying agent.
