Set elements

from Wikipedia, the free encyclopedia

A quantity element (also macro element ) is a mineral substance which, in contrast to the trace element (micro element ), occurs in various media in a mass fraction of more than 50 mg per kilogram. Because bulk elements are usually ionized in an aqueous medium, ie as positively (Na + , K + , Ca 2+ , Mg 2+ ) or negatively (Cl - , HPO 4 2− , SO 4 2− ) charged particles, they are called Called electrolytes .

The quantity elements important for the human organism are:

  • Magnesium (Mg) - part of bones, teeth, numerous enzymes and energy-rich phosphate compounds
  • Chlorine (Cl) - together with sodium u. a. important for water balance, acid / base balance; Chlorine is a component of gastric hydrochloric acid (HCl)

The four basic elements of the organisms hydrogen , carbon , nitrogen and oxygen do not belong to the minerals and thus also not to the quantity elements .
The entire biomass consists of 99% of these four elements.
