Nitrogen is a vital component of the human body and is essential for life. It's a key building block of proteins, DNA, and RNA.
How nitrogen is important to humans
Nitrogen is a main body component and is required for both tissue protein synthesis and the production of several nitrogenous compounds involved in a variety of functions (hormones, immune mediators, neurotransmitters, antioxidant defences, etc.)
Protein synthesis: Nitrogen is a main component of proteins, which are essential for growth, hormones, brain function, and the immune system
DNA: Nitrogen is a key building block of DNA, which determines our genetics
RNA: Nitrogen is a core ingredient of nucleic acids that form RNA
