Phosphorus-based compounds are chemical substances that contain the element phosphorus. These compounds play essential roles in various biological processes, including energy transfer and the formation of DNA and RNA. Common examples include phosphates, which are vital for plant growth and are often used in fertilizers. In addition to their biological importance, phosphorus-based compounds are also used in industrial applications. They can be found in detergents, flame retardants, and food additives. The versatility of these compounds makes them significant in both environmental and commercial contexts.
