Selenium - Wikipedia

Although it is toxic in large doses, selenium is an essential micronutrient for animals. In plants, it occurs as a bystander mineral , sometimes in toxic proportions in forage (some plants may accumulate selenium as a defense against being eaten by animals, but other plants, such as locoweed, require selenium, and their growth indicates the presence of selenium in soil). See more on plant nutrition below. Selenium is a component of the unusual amino acids selenocysteine and selenomethionine. In humans, s
