nac glutathione reaction has direct antioxidant properties on oxidant species (e.g. OH • ) N-Acetylcysteine (NAC): Impacts on Human

Organisms contain two other enzymes, glutathione peroxidase (GPx), of which there are several isoforms, and catalase (CAT), which are involved in the decomposition of hydrogen peroxide to oxygen and water

It has also been reported that the -glutamylcysteine synthetase is not the limiting step in plants under heavy metal stress conditions and overexpression of a bacterial glutathione synthetase gene alone in Indian mustard results in higher concentrations of glutathione in the transgenic plant 31

The main geological features interpreted are the MDP, the MCOT and the MB

Glutathione can shift melanogenesis toward pheomelanin, potentially leading to lighter skin or hair and can also reduce eumelanin production by inhibiting tyrosinase, an enzyme crucial for melanin synthesis
