What chemical elements are part of a cell?

The cell contains about 70 elements of the periodic system of D. I. Mendeleev. Of these, the main part (98%) is accounted for by macroelements – carbon, hydrogen, oxygen, nitrogen, which together with sulfur and phosphorus form a group of bioelements.
Elements such as sulfur, phosphorus, potassium, sodium, iron, calcium and magnesium account for only 1.8% of the substances that make up the cell.
In addition, the cell composition includes trace elements iodine (I), fluorine (F), zinc (Zn), copper (Cu), which make up 0.18% of the total mass, and micronutrients – gold (Au), silver (An), platinum (P) included in the cells in an amount up to 0.02%.

Chemical element Value
Oxygen Included in water and all biological compounds
Carbon Included in all biological compounds
Hydrogen and nitrogen Structural components of organic substances
Phosphorus Included in DNA
Sulfur Serves as a catalyst for chemical reactions in the cell.
Iron Included in hemoglobin
Calcium Structural cell element, responsible for the exchange of ave. In the cell
