GlossaryGlutathione Peroxidase (GPx)

enzyme that protects cells by reducing harmful peroxides

Glutathione Peroxidase (GPx) is an enzyme that protects cells from oxidative damage by reducing harmful peroxides, such as hydrogen peroxide, into water and oxygen. It uses glutathione as a substrate to neutralize these peroxides, playing a crucial role in maintaining cellular health and preventing damage that can lead to conditions like alopecia and other oxidative stress-related diseases.
