trace elements are chemical elements that occur in the body with a concentration of less than 50mg per kg. The trace elements include chromium, cobalt, iron, fluorine, iodine, copper, manganese, molybdenum, selenium, silicon, vanadium, zinc and tin.
Many trace elements are part of vital proteins and hormones, or serve as a catalyst for chemical reactions. The exact interactions of many trace elements, as well as their importance for the metabolism of humans, could not yet be completely clarified. Although all elements can be detected in low concentration, but whether they all have a function, or only accidentally get into our organism is unclear.
By the way: Elements with more than 50mg per kg belong to the quantity elements.
Table: Overview of the most important trace elements
|trace element||Function in the body|
|Cobalt (Co)||Component of vitamin B12|
|Iron (Fe)||Important component of hemoglobin|
|Fluorine (F)||So far, there are no verified studies on fluorides that demonstrate any essential benefit|
|Iodine (I)||Component of thyroid hormones|
|Manganese (Ma)||Cofactor for transferases, ligases and hydrolases|
|Molybdenum (Mo)||enzyme catalyst|
|Selenium (Se)||Cofactor in the production of thyroid hormones; Component of the amino acid selenocysteine|
|Silicon (Si)||Necessary for the synthesis of structural proteins (eg collagen and elastin)|
|Zinc (Zn)||Component of many hormones and enzymes (including RNA polymerase)|
