Selenium is a chemical element

Selenium is a chemical element with symbol Se and atomic number 34.

Exists in two forms: a silvery metal or a powder.

Red selenium is an amorphous, glass-like solid, whereas grey selenium is a soft, bluish-grey metal.

Grey selenium is a semi-conductor. Its electrical conductivity increases on exposure to light, reverting to its normal value in darkness.

What role does selenium play in the body?

1. can prevent cancer and cancer

After surgery, cancer patients can be properly supplemented with selenium, which can effectively control the deterioration of the disease, reduce the toxic and side effects of radiotherapy and chemotherapy, and also improve the efficacy of anti-cancer drugs.

2. Protect the heart muscle and liver

Appropriate selenium supplementation in patients with myocardial infarction can improve cardiac function indexes to a certain extent, increase the level of high-density lipoprotein, and reduce thrombosis. Selenium has a certain antioxidant effect, can protect liver cells, reduce the damage caused by toxins to the liver, delay the occurrence of cirrhosis or liver cancer, but also can delay aging.

3. Help control blood sugar

Lack of selenium in vivo can cause damage to the synthesis of islet cells and affect the secretion function of islet. Appropriate selenium supplementation can protect islet cells, inhibit their oxidation process, and reduce or delay the complications of diabetes.

4. anti-aging and protect eyesight

Selenium activates antioxidants in the body, defusing the damage caused by oxidation, reducing the risk of disease and prolongs life. Studies have found that the higher levels of selenium in the blood, the longer people live.

5. can repair and protect cells

Selenium is an antioxidant substance, which can maintain the basic metabolic activities in the body. Selenium also protects cell membrane structures, not only protecting vital organs such as the heart, kidneys, lungs and liver, but also protecting the eyes. Lack of selenium can lead to poor vision and an increased risk of retinopathy, cataracts and night blindness.

6. improve the oxygen carrying capacity of cells

Selenium can protect red blood cells, avoid the oxidation of hemoglobin in red blood cells, enhance their ability to carry oxygen, especially suitable for heavy mental workers, avoid brain hypoxia, relieve brain fatigue. In addition, selenium can reduce the toxic side effects of some chemical carcinogens and pesticides, and help detoxify and detoxify the body.

7. Enhance immunity

Selenium can enhance immunity, enhance the ability to recognize viruses, foreign bodies and lesions, but also improve the proliferation of immune cells, promote the production of antibodies, and improve the level of antibodies in the blood. In addition, it can also improve the ability of phagocytosis and sterilization of immune cells, improve the overall immune function, and help the body fight viruses and various infections.

Application of the selenium:

Together with cadmium and sulphur, selenium is a component of pigments used in plastic colouring.

In pigments used in Paint, enamels, ink and rubber

Zinc selenide is also used in windows for infrared optical devices.

Selenium can be found in new CIGS photovoltaic technologies (cadmium indium gallium selenide)

Solid state memory in electronic applications.

Selenium is an essential micronutrient for animal

It is also used to make photographic toner, photo cells, electric eyes and light meters for cameras.

Selenium is used with bismuth in brasses and as an additive to stainless steel. When selenium is added to iron and copper based metals it improves their machinability.

Red Pigments

Light-sensitive materials, glass colorants/decolorants, pigments, CIGS solar cells, X-ray detector

It is therefore useful in photocells, solar cells and photocopiers. It can also convert AC
