Each cell consists of macroelements, microelements, ultramicroelements, water and mineral salts • macroelements are divided into two groups
~ the largest (98%) consists of hydrogen, oxygen, carbon and nitrogen
~ carbohydrates and lipids contain: hydrogen, oxygen and carbon ~ protein contains hydrogen, oxygen, carbon and nitrogen
~ a smaller group which includes: sulfur, phosphorus, potassium, calcium, magnesium, sodium and chlorine. sulfur is a part of proteins. phosphorus is part of nucleic acids. potassium, calcium and sodium ensure contraction of the heart muscle. calcium is involved in blood clotting.
• microelements: zinc, iodine, cobalt and manganese; these elements are contained in the cell in small quantities.
• Ultramicroelements are contained in the cell in negligible amounts. This includes Gold and Silver.
• water is necessary for the life of the cell, maintaining its vital functions and is one of the main components of the cell
• mineral salts are contained in the cell in the form of ions
