Glutathione

Properties

Product Details

L-Glutathione is a tripeptide composed of the amino acids glutamic acid, cysteine, and glycine. It is a major endogenous antioxidant naturally produced by cells and plays a fundamental role in maintaining cellular homeostasis.

In a research context, L-Glutathione is a critical tool for investigating cellular defense mechanisms against oxidative stress. It is widely used in *in vitro* models to study detoxification pathways, redox signaling, and the cellular response to toxins and free radicals. Its role as a primary antioxidant makes it a subject of extensive research in cellular biology and toxicology.

L-Glutathione vs. Reduced Glutathione

In scientific literature and laboratory contexts, the terms “L-Glutathione” and “Reduced Glutathione (GSH)” are often used interchangeably. Both refer to the same molecule in its active, antioxidant state. The “L” denotes the stereoisomer of the glutamic acid residue, which is the biologically active form. “Reduced” refers to the state of the thiol group on the cysteine residue, which is capable of donating an electron to neutralize free radicals. The product supplied is the stable, reduced form of L-Glutathione, suitable for all standard research applications investigating its antioxidant properties.
