Selenium is A necessary trace component that is certainly involved with the protection towards the toxicity of reactive oxygen species, the regulation of the redox state of cells and within the regulation of thyroid hormone metabolism.

Its deficiency has brought on serious well being effects in human, such as Keshan’s condition, a most likely fatal sort of cardiomyopathy (disease of the center muscle mass) that influences younger Females and baby. The most important function of selenium is in the form of antioxidant selenoproteins or selenoenzymes for instance glutathione peroxidase, thioredoxin reductase. Glutathione peroxidase performs a big purpose in guarding cells against oxidative injury from reactive oxygen species (ROS) and reactive nitrogen species (RNS), which consist of superoxide, hydrogen peroxide, hydroxyl radicals and nitric oxide and peroxynitrite. The pentose phosphate pathway helps glutathione peroxidase, an enzyme which contains selenium as the trace component, in shielding erythrocytes versus haemolysis. The antioxidant activity of selenium aids in avoidance of cardiovascular illnesses and assists in upkeep of appropriate immunity. It's been described that the antioxidant activity of selenoenzymes could stop the formation of oxidized LDL and consequently decrease the incidence of heart disorders. However epidemiological research don't firmly affirm The reality that lower Se stage is associated with improved risk of heart illnesses. A recent research in United states also confirmed precisely the same outcome (Stranges et al. 2006). But eating plan full of Se has been observed to cut back the results of reperfusion and when Se turns into deficient, it might considerably impair intrinsic myocardial tolerance to ischemia.
