Selenium is an essential trace element which plays an important role in human immune regulation and disease prevention. Plants absorb inorganic selenium (selenite or selenate) from the soil and convert it into various organic selenides (such as seleno amino acids, selenoproteins, and volatile selenides) via the sulfur metabolic pathway. These organic …

What Is Selenite? Selenite is a type of crystal that is known for its translucent appearance and pearly white or clear color. It is composed of calcium sulfate dihydrate and is often commonly found in various sedimentary rocks and environments. The name "selenite" is derived from the Greek word "selēnitēs," which means "moonstone" or "moon rock."
