glutathione peroxidase वाक्य
उदाहरण वाक्य
मोबाइल
- Most importantly, researchers have successfully genetically engineered GSTZ1 to mimic one of the most significant antioxidant enzymes, glutathione peroxidase ( GPX ).
- Surprisingly, glutathione peroxidase 1 is dispensable, as mice lacking this enzyme have normal lifespans, but they are hypersensitive to induced oxidative stress.
- The skin contains several antioxidants, including vitamin E, coenzyme Q10, ascorbate, carotenoids, superoxide dismutase, catalase, and glutathione peroxidase.
- It is a component of the antioxidant enzymes glutathione peroxidase and thioredoxin reductase ( which indirectly reduce certain oxidized molecules in animals and some plants ).
- The glutathione peroxidase family of enzymes ( GSH-Px ) catalyze certain reactions that remove reactive oxygen species such as hydrogen peroxide and organic hydroperoxides:
- An example of this is ceruloplasmin, a protein that functions as an oxidase in copper metabolism and moonlights as a copper-independent glutathione peroxidase.
- 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.
- 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.
- Several antioxidant enzymes such as superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glutathione S-transferase etc . protect DNA from oxidative stress.
- Thioredoxin belongs to a structural family that includes glutaredoxin, glutathione peroxidase, bacterial protein disulfide isomerase DsbA, and the N-terminal domain of glutathione transferase.
- Reduced glutathione reduces the oxidized form of the enzyme glutathione peroxidase, which in turn reduces hydrogen peroxide ( H2O2 ), a dangerously reactive species within the cell.
- The antioxidant enzyme glutathione peroxidase 4 ( GPx4 ) belongs to the family of glutathione peroxidases, which consists of 8 known mammalian isoenzymes ( GPx1-8 ).
- In one study, the activity of glutathione peroxidase along with other antioxidant enzymes such as superoxide dismutase and catalase was not associated with coronary heart disease risk in women.
- It performs its functions as antioxidant in the glutathione peroxidase pathway, and it protects cell membranes from oxidation by reacting with lipid radicals produced in the lipid peroxidation chain reaction.
- Shukla, V . K . S .; Srivastava, K . C . : Erythrocyte glutathione peroxidase and serum lipid pattern : A comparison between Indian immigrants and Danes.
- Glutathione peroxidase ( GPx ) activity was significantly higher in the DOW group than in the control group, while there was no difference between the surface seawater and control groups.
- This is in line with findings showing that ?-tocopherol, but not water-soluble antioxidants, efficiently protects glutathione peroxidase 4 ( GPX4 )-deficient cells from cell death.
- Mice genetically engineered to lack glutathione peroxidase 1 ( Gpx1 " / " mice ) are grossly phenotypically normal and have normal lifespans, indicating this enzyme is not critical for life.
- The alpha class genes, which are located in a cluster on chromosome 6, are highly related and encode enzymes with glutathione peroxidase activity that function in the detoxification of lipid peroxidation products.
- Glutathione peroxidase 1 is characterized in a polyalanine sequence polymorphism in the N-terminal region, which includes three alleles with five, six or seven alanine ( Ala ) repeats in this sequence.
