Glutathione, a high-quality research chemical peptide, CAS No. 70-18-8, is a lyophilized powder.



Reduced L-Glutathione (GSH) Product Introduction

Reduced L-glutathione, abbreviated as GSH, CAS number 70-18-8, is a natural bioactive tripeptide composed of L-glutamic acid, L-cysteine, and glycine. As one of the most important endogenous antioxidants in the human body and a core functional raw material in the chemical and pharmaceutical industries, GSH has gained widespread recognition and application in the global market, especially in the fields of pharmaceuticals, cosmetics, health products, and biochemical research. This product is a high-purity white crystalline powder with excellent water solubility and stable chemical properties under appropriate storage conditions, making it an ideal raw material for various downstream production and research scenarios.

Structurally, reduced L-glutathione exists in a biologically active reduced state, which is completely different from oxidized glutathione (GSSG). Only reduced glutathione can retain its complete biological activity, thereby performing a series of key physiological and chemical functions. Its molecular formula is C₁₀H₁₇N₃O₆S, with a molecular weight of 307.33. It is readily soluble in water but insoluble in most organic solvents, which greatly facilitates its preparation and application in water-based products and experimental systems. This product meets stringent quality standards, with a GSH content ≥99.0%, low impurity content, and complies with international raw material specifications, ensuring its reliability in industrial production and scientific research.

The core value of reduced L-glutathione lies in its powerful antioxidant and detoxification functions. As a free radical scavenger, it effectively removes reactive oxygen species and free radicals in the body, protecting cell membranes, mitochondria, and DNA from oxidative damage. It can also regenerate antioxidants such as vitamin C and vitamin E in the body, forming a complete antioxidant defense system. In terms of detoxification, it is a key substance in the liver detoxification process, capable of binding with heavy metals, drug toxins, and metabolic waste, helping the liver complete toxin metabolism and reducing the damage of harmful substances to the body. Furthermore, it can inhibit the activity of tyrosinase, effectively regulating melanin production, and has become a commonly used functional ingredient in skincare products. It also plays a crucial role in maintaining the activity of immune cells, supporting the normal functioning of the body's immune system.

Reduced L-glutathione has a wide range of applications, covering many high-demand industries worldwide. In the pharmaceutical industry, it is an important raw material for injectable drugs, widely used as an adjunct treatment for drug-induced liver injury, viral hepatitis, and radiotherapy/chemotherapy, demonstrating stable efficacy and high safety. In the cosmetics industry, it is added to antioxidant, brightening, and anti-aging skincare products, helping to improve dull skin and delay skin aging, making it highly favored by cosmetic manufacturers worldwide. In the health supplement industry, it is used as a core ingredient in oral supplements, often combined with N-acetylcysteine ​​(NAC) to improve bioavailability and help consumers supplement endogenous antioxidants. In the field of biochemical research, it is an important reagent for cell culture and in vitro biochemical experiments, providing stable support for scientific research.

Regarding storage and packaging, reduced L-glutathione is prone to oxidation and discoloration when exposed to air; therefore, it needs to be stored in a sealed, light-proof environment at a temperature of 2-8°C, avoiding prolonged exposure to air and high temperatures. The product is packaged in 1500mg*10-vial vials, with packaging specifications customizable to customer needs for easy transportation and storage. Under proper storage conditions, this product has a shelf life of 24 months, ensuring customers can use it without quality issues within the expiration date.
