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.
Function. Thyroid peroxidase is a type of enzyme produced in the thyroid. This enzyme plays a vital role in helping the thyroid gland produce hormones, specifically triiodothyronine (T3) and thyroxine (T4) hormones.ormones are released by the thyroid that help to that certain bodily functions--such as blood pressure, metabolism and heart functions-- are working properly. Thyroid peroxidase (TPO) is an antibody that can help or disrupt the production of hormones, depending on their working levels.
