Briefly discuss selenium's bioavailability, absorption, and functions
Selenium's bioavailability is high, and its intestinal absorption is not regulated.Once absorbed, selenium circulates in the blood to the body's cells. Some selenium is incorporated into amino acids, which are subsequently used to make selenoprotein molecules. There are at least 14 selenoproteins in the body. One group of enzymatic selenoproteins helps protect against oxidative damage and may protect against certain types of cancer, but more research is required to understand the role of selenium in disease prevention. The kidneys maintain blood selenium concentrations, and excess amounts are simply excreted in the urine. When consumption is high, selenium can also be expelled in the breath, causing a garlicky odor.
