glutathione is a tripeptide antioxidant Glutathione C10h17n3o6s Tripeptide Antioxidant Structural
Description
In the GST family, early studies demonstrated that the GSTP1 gene plays an important role in several cellular processes, including catalysis and deoxylation of electrophilic compounds, oxidative stress regulation, cell signaling and carcinogenesis (25,26)

It is funnel-shaped with 30 long in small catalases [30, 48], while in large catalases that channel is replaced by an elongated, constricted, and possibly bifurcated channel that includes the C-terminal domain of adjacent subunit [3, 30]
