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.
Bacterial glutathione transferases (GSTs; EC 2.5.1.18) are part of a superfamily of enzymes that play a crucial role in cellular detoxification. [2] The primary role of GSTs is to catalyze the conjugation of glutathione (GSH) with the electrophilic centers of a wide variety of molecules. The most commonly known substrates of GSTs are xenobiotic ...

Glutathione peroxidase ( GPx) ( EC 1.11.1.9) is the general name of an enzyme family with peroxidase activity whose main biological role is to protect the organism from oxidative damage. [2] The biochemical function of glutathione peroxidase is to reduce lipid hydroperoxides to their corresponding alcohols and to reduce free hydrogen peroxide ...
Three forms of PTH are measured in this test. The exact normal ranges vary based on the lab doing the testing. The results are described in picograms per milliliter (pg/mL). Discuss the results ...
A recent study suggests that the normal range should be more like 0.45 to 4.12 mU/L. TSH can vary wildly based on your age, sex, and stage of life. For example, a 29-year-old woman may have normal ...
Fasting blood glucose measures the amount of glucose ( sugar) in your blood to test for diabetes or prediabetes. Typical fasting time: At least 8 hours. Lipid profile checks the level of ...
Glutamate–cysteine ligase (GCL) EC 6.3.2.2 ), previously known as γ-glutamylcysteine synthetase (GCS), is the first enzyme of the cellular glutathione (GSH) biosynthetic pathway that catalyzes the chemical reaction : L -glutamate + L -cysteine + ATP γ-glutamyl cysteine + ADP + P i. GSH, and by extension GCL, is critical to cell survival.
