Glutathione peroxidase (GPx) is an enzyme that protects the body from oxidative damage from free radicals. Antioxidants, like GPx, are enzymes and nutrients that block some of the damage caused by free radicals. These free radicals are what causes the aging process, some cancers (according to studies), cardiovascular diseases, and athritis.GPx, which contains selenium, protects the body against oxidative stress through scavenging and inactivating hydrogen and lipid peroxides. GPx should not be confused with glutathione (GSH).
There are eight members of the GPx family that have been identified in humans: GPx1, GPx2, GPx3, GPx4, GPx5, Gpx6, GPx7, and GPx8. Of the eight, GPx1 is the most abundant in the human body.
Glutathione peroxidase(GPx) is a natural antioxidant and can be found in almost all fruits and vegetables.
U of M researchers find natural antioxidant can protect against cardiovascular disease
University of Minnesota Medical School researchers have collaborated with the School of Public Health and discovered an enzyme that, when found at high levels and alongside low levels of HDL (good cholesterol), can dramatically reduce the risk of cardiovascular disease.
The enzyme – glutathione peroxidase, or GPx3 – is a natural antioxidant that helps protect organisms from oxidant injury and helps the body naturally repair itself. Researchers have found that patients with high levels of good cholesterol, the GPx3 enzyme does not make a significant difference. However, those patients with low levels of good cholesterol, the GPx3 enzyme could potentially be a big benefit. The enzyme's link to cardiovascular disease may also help determine cardiovascular risk in patients with low levels of good cholesterol and low levels of the protective GPx3.
