In human body, it is found in combined state not like atmospheric Nitrogen. . Nitrogen atoms are found in all proteins and DNA. Nitrogen is a component of proteins, nucleic acids, and other organic compounds. It is used to make amino acids in our body which in turn make proteins. It is also needed to make nucleic acids, which form DNA and RNA. Human or other species on earth require nitrogen in a ‘fixed’ reactive form. It is necessary for the food production process. As, we know nitrogen makes up a large part of the Earth’s atmosphere. Human can’t utilize nitrogen through respiration, but can absorb through the consumption of plants or animals that have consumed nitrogen rich vegetation. The air we breathe is around 78% nitrogen, so it is obvious that it enters our body with every breath. This nitrogen helps in protein synthesis, amino acids that influence growth, hormones, brain functions and the immune system. The foods with the highest amounts of nitrogen are vegetables and fruit such as lettuce, radish, rhubarb and spinach. Dairy products, meats and fish contain a good amount of nitrogen, but not at the levels of vegetables. Cured meat such as sausage, which is preserved with sodium nitrate or nitrate, are yet another way for people to get nitrogen into their bodies.
