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.
The Quick view... The tri-peptide glutathione or (GSH) is a combination of the amino acids glutamate (glutamic acid), L-cysteine, and glycine. Each and every cell in the body takes these raw ingredients to manufacture GSH.It is a very small protein (made of three amino acids) and is essential for life.he Quick view...
