Nitrogen exists in the free and in the combined form in the atmosphere of the earth. In the free state it occupies about 80% by volume of air. In the combined form, it is present as ammonia and all ammonium compounds, in nitric acid and in all nitrates, nitrites and in all living ..

The living cells contain specific macromolecules with a high molecular weight and a poor solubility. Generally in a cell, macromolecules are represented by polysaccharides, proteins, nucleic acids and enzymes. These compounds are formed by polymerisation of micromolecu..
