WebGlutathione (GSH) is often referred to as the body's master antioxidant. Composed of three amino acids - cysteine, glycine, and glutamate - glutathione can be found in virtually every cell of the human body. The highest concentration of glutathione is in the liver, making it critical in the body's detoxification process. WebGlutathione redox cycle as antioxidant mechanism. Superoxide dismutase (SOD) has promoted the generation of hydrogen peroxide (H 2 O 2 ), at least temporarily. However, …
WebGlutathione (GSH or reduced glutathione) is a tripeptide of gamma-Glutamyl-cysteinylglycine and the predominant intracellular antioxidant in many organisms including humans. … WebAlthough the antioxidant properties of GSH are known in some detail, there is little information on the ability of SAM to interact directly with reactive oxygen species (ROS) produced during ischaemia-reperfusion injury. This work compares the interaction of SAM and GSH with several ROS which may be formed during ischaemia-reperfusion.
