Selenium plays a crucial role in the microsomal mixed-function oxidase system, acting as an essential electron carrier. This function makes it closely linked to the synthesis and metabolism of various biologically active compounds, as well as the detoxification and biotransformation of exogenous substances such as drugs, toxins, and even carcinogens. Its involvement in these processes highlights its importance in maintaining cellular health and metabolic balance.
In addition to its role in oxidation-reduction reactions, selenium is also a key component in the synthesis of coenzyme A and coenzyme Q, both of which are vital for energy production and cellular respiration. It is also found in cytochrome complexes that participate in the electron transport chain, further emphasizing its significance in the tricarboxylic acid cycle and overall energy metabolism. Moreover, selenium supports protein synthesis, contributing to the growth and maintenance of tissues throughout the body.
When combined with vitamin E, selenium helps protect cells from oxidative damage, particularly in animals. This synergy is especially important in preventing reproductive issues, such as infertility or miscarriage. However, when both selenium and vitamin E are deficient, the body becomes vulnerable to oxidative stress. The accumulation of peroxides can lead to damage of cell membranes, resulting in the loss of cellular integrity. This damage affects various types of cells, including skeletal muscle, heart muscle, liver cells, pancreatic cells, capillary endothelial cells, and nerve cells.
As a result, animals may exhibit clinical signs such as muscular dystrophy, muscle and stomach atrophy, pancreatic degeneration, exudative diathesis, and brain softening. These conditions are commonly observed in poultry and highlight the critical role of selenium in maintaining proper physiological function and preventing disease. Ensuring adequate selenium intake through diet is therefore essential for animal health and productivity.
