Nitrogen-containing compounds are chemical substances that include nitrogen atoms in their molecular structure. These compounds can be found in various forms, such as amines, amides, and nitriles. They play essential roles in biological processes, including the formation of proteins and nucleic acids, which are vital for life. Many nitrogen-containing compounds are also important in agriculture and industry. For example, fertilizers often contain nitrogen to promote plant growth. Additionally, some nitrogen compounds are used in the production of explosives and pharmaceuticals, highlighting their diverse applications in everyday life.
