It is the most important low-molecular-weight thiol in mammalian cells during oxidative stress. Discovered in 1921 and its chemical structure determined in 1930, Dr. El Minder, a renowned American nutrition and health expert, referred to glutathione as an anti-aging amino acid with triple effectiveness. It is also known as the "master antioxidant of nature." Glutathione appears as colorless, transparent, and elongated crystalline particles. It is soluble in water, dilute alcohols, liquid ammonia, and dimethylformamide, but insoluble in ethanol, ether, and acetone. In its solid state, it is stable; however, its aqueous solution is easily oxidized to the oxidized form of glutathione in the air. It is widely found in bread yeast, wheat germ, animal liver, chicken blood, pig blood, tomatoes, pineapples, and cucumbers, with the highest concentrations in wheat germ and animal liver (100–1000 mg/100 g). Glutathione has various functions, including antioxidant properties, free radical scavenging, detoxification, immune system enhancement, anti-aging, anti-cancer effects, and protection against radiation damage. It also helps white blood cells kill bacteria, prevents the oxidation of vitamins C and E, and helps prevent strokes and the formation of cataracts. Additionally, glutathione binds carcinogens and excretes them from the body through urine. The liver is the most important detoxification organ in the body, and the abundant glutathione (GSH) it contains protects the liver's synthesis, detoxification, and estrogen inactivation functions. Glutathione is the primary antioxidant that counteracts the damage caused by free radicals, which are factors contributing to aging and diseases. When the liver is damaged (e.g., due to various liver diseases), the body consumes large amounts of GSH to aid in self-repair and detoxification, leading to a significant decrease in glutathione levels. At this time, taking glutathione supplements can help the damaged liver repair itself. Therefore, glutathione-based medications are suitable for viral hepatitis (such as hepatitis A and B), alcoholic liver disease, drug-induced liver disease, fatty liver, and other liver conditions, making them effective for liver protection. **Antioxidants:** Many biochemical reactions in the body are catalyzed by enzymes, most of which use thiol groups as their active sites. The state of these thiol groups determines the activation and inhibition of enzyme activity. Glutathione acts as a natural activator for these enzymes, reducing H2O2 generated by cellular metabolism to H2O, thereby removing free radicals from the body. Free radicals can damage cell membranes, accelerate aging, and induce tumors or arteriosclerosis. Glutathione also protects cells from peroxidation and improves the skin's antioxidant capacity, giving it a radiant appearance. Aging, infections, poisoning, exogenous toxins, oxidative stress, and attacks by electrophilic compounds can all reduce the level of GSH in the cytoplasm. This reduction occurs very early in the process of apoptosis, and detecting glutathione levels can help identify apoptosis early on. Glutathione also prevents the formation of oxidized lipids and protects flavor nucleotides (such as inosine monophosphate and guanosine monophosphate) in foods (e.g., fish paste, sausages, soy sauce) from decomposing and losing their flavor. **Uses:** Glutathione has multiple functions, including antioxidant properties, free radical scavenging, detoxification, immune system enhancement, anti-aging, anti-cancer effects, and protection against radiation damage.
