Glutathione Biosynthesis Enhancement via Precursor Function (None)

Target
None
Molecular classification
Metabolic pathway, Enzyme regulation
01

Overview

Glutathione biosynthesis enhancement via precursor function refers to increasing intracellular glutathione (GSH) levels by supplying or modulating the availability of its amino acid precursors—primarily cysteine—and regulating the activity or expression of key biosynthetic enzymes like Glutamate–Cysteine Ligase (GCL) and Glutathione Synthetase (GS). It is a therapeutic strategy to combat oxidative stress and improve cellular function in various diseases.
