Nitrogen is a constituent of molecules in every major pharmacological drug class, including antibiotics. Many drugs are mimics or prodrugs of natural nitrogen-containing signal molecules: for example, the organic nitrates nitroglycerin and nitroprusside control blood pressure by being metabolized to nitric oxide.itrogen is present in all known living organisms, in proteins, nucleic acids, and other molecules. It typically makes up around 4% of the dry weight of plant matter, and around 3% of the weight of the human body.
Some bacteria in the water change this ammonia to produce nitrite which is then converted by other bacteria to nitrate. Nitrates (NO 3-) are an oxidized form of nitrogen and are formed by combining oxygen and nitrogen. Nitrates also come from the earth. Soil contains organic matter, which contains nitrogen compounds.nimals get nitrogen by eating plants and other animals. Just like animals, plants require nitrogen to grow and survive. But they do not get nitrogen by consuming proteins like animals do. Plants get nitrogen from water and from the soil. They get nitrogen by absorbing it in the form of nitrates and ammonium.
