Glutathione (GSH, / ˌ ɡ l uː t ə ˈ θ aɪ oʊ n /) is an organic compound with the chemical formula HOCOCH(NH 2)CH 2 CH 2 CONHCH(CH 2 SH)CONHCH 2 COOH. It is an antioxidant in plants , animals , fungi , and some bacteria and archaea .
Glutathione S-transferases have great significance in herbicide detoxification and tolerance in agriculture and their induction by herbicide antidotes ('safeners') is the decisive step for the induction of herbicide tolerance in many crop plants.
Glutathione synthetase (GSS) (EC 6.3.2.3) is the second enzyme in the glutathione (GSH) biosynthesis pathway. It catalyses the condensation of gamma-glutamylcysteine and glycine, to form glutathione. [2] Glutathione synthetase is also a potent antioxidant. It is found in many species including bacteria, yeast, mammals, and plants. [3]
Glutathione reductase (GR) also known as glutathione-disulfide reductase (GSR) is an enzyme that in humans is encoded by the GSR gene.Glutathione reductase (EC 1.8.1.7) catalyzes the reduction of glutathione disulfide to the sulfhydryl form glutathione (), which is a critical molecule in resisting oxidative stress and maintaining the reducing environment of the cell.
Glutathione peroxidase 1 is the most abundant and is a very efficient scavenger of hydrogen peroxide, while glutathione peroxidase 4 is most active with lipid hydroperoxides. Surprisingly, glutathione peroxidase 1 is dispensable, as mice lacking this enzyme have normal lifespans, [123] but they are hypersensitive to induced oxidative stress. [124]
For US food and dietary supplement labeling purposes, the amount in a serving is expressed as a percent of Daily Value (%DV). For selenium labeling purposes, 100% of the Daily Value was 70 μg, but as of 27 May 2016 it was revised to 55 μg. [34] [35] A table of the old and new adult daily values is provided at Reference Daily Intake.
WASHINGTON (Reuters) -The Justice Department late on Wednesday asked a U.S. appeals court to reject an emergency bid by TikTok to temporarily block a law that would require its Chinese parent ...
GCL is exclusively located in plastids, and glutathione synthetase (GS) is dual-targeted to plastids and cytosol, thus GSH and gamma-glutamylcysteine are exported from the plastids. [28] Studies also shown that restricting GCL activity to the cytosol or glutathione biosynthesis to the plastids is sufficient for normal plant development and ...
