About this compound
More on L-Glutathione.
Reduced L-Glutathione (GSH) is a naturally occurring tripeptide composed of cysteine, glutamate, and glycine. Because of its central role in cellular redox balance and antioxidant defense, glutathione has become an important subject of research across biochemistry, oxidative stress, and cellular metabolism.
Supplied as a 1500mg lyophilized vial, this research-grade L-Glutathione is designed for laboratory applications where stability, purity, and batch documentation are important.
What Is L-Glutathione?
Glutathione is found throughout the body and is particularly important in maintaining the balance between oxidized and reduced molecules inside cells. The reduced form, GSH, contains a reactive sulfur group that allows it to participate in redox reactions and interact with reactive oxygen species.
Its broad biological role has led researchers to study glutathione in areas ranging from oxidative stress and cellular defense to metabolic and liver research.
Why Is Glutathione Studied?
Researchers commonly investigate L-Glutathione through several interconnected pathways:
Antioxidant & Redox Research
GSH participates in cellular antioxidant systems by helping maintain an appropriate redox environment. Its ability to undergo oxidation and reduction makes it a useful molecule for studying oxidative stress and cellular defense mechanisms.
Because glutathione is involved in multiple biochemical processes, researchers have examined its relationship with cellular aging, mitochondrial function, immune signaling, metabolic regulation, and other areas of molecular biology.
Documentation: Batch-specific Certificate of Analysis
Storage: Follow the supplied laboratory storage recommendations
The lyophilized format helps protect the compound during storage and transport. Researchers should follow appropriate laboratory procedures when preparing and handling the material.
Quality & Batch Verification
Quality control is an important consideration when working with research compounds. Each lot is independently tested for purity, with batch-specific documentation available through the accompanying Certificate of Analysis.
This provides researchers with analytical information that can be referenced when documenting experimental materials and maintaining reproducibility between studies.
Research Applications
L-Glutathione may be investigated in laboratory models involving:
Oxidative stress and redox biology
Reactive oxygen species (ROS)
Cellular antioxidant defense
Glutathione S-transferase activity
Liver and metabolic research
Mitochondrial biology
Cellular aging models
Xenobiotic metabolism
Frequently Asked Questions
What form of glutathione is provided?
The product contains reduced L-Glutathione (GSH) in lyophilized powder form.
How much is included?
Each vial contains 1500mg of L-Glutathione.
How is purity verified?
