CAS Number: 70-18-8
Sequence: γ-L-Glutamyl-L-Cysteinylglycine (GSH)
Chemical Description
Glutathione (GSH) is a ubiquitous, low-molecular-weight tripeptide found in virtually all mammalian cells. It is essential for maintaining cellular redox homeostasis, primarily through the dynamic cycling between its reduced (GSH) and oxidized (GSSG) forms. This balance is critical for protecting sulfhydryl groups on proteins and enzymes from reactive oxygen species (ROS). Glutathione is a cornerstone molecule in research focused on detoxification, free radical scavenging kinetics, and enzymatic activity, particularly for Glutathione S-transferases (GSTs).
