Internal structure: Scientists think that on average, the Martian core is about 1,800 and 2,400 miles in diameter (3,000 and 4,000 km), its mantle is about 900 to 1,200 miles (5,400 to 7,200 km) wide and its crust is about 30 miles (50 km) thick.
Glutathione peroxidase (GPx) (EC 1.11.1.9) is the general name of an enzyme family with peroxidase activity whose main biological role is to protect the organism from oxidative damage.owever, glutathione peroxidase 4 knockout mice die during early embryonic development. Some evidence, though, indicates reduced levels of glutathione peroxidase 4 can increase life expectancy in mice.
Glutathione (GSH) is often referred to as the body's master antioxidant. Composted of three amino acids-cysteine, glycine, and glutamate-glutathione can be found in virtually every cell of the human body.The highest concentration of glutathione is in the liver, making it critical in the body's detoxification process.s the generation of free radicals exceeds the body's ability to neutralize and eliminate them, oxidative stress occurs. A primary function of glutathione is to alleviate this oxidative stress.
