Nitrogen is a constituent of proteins.
Nitrogen is a naturally occurring element that essential for growth and reproduction in both plants and animals.
It is found in amino acids that make up proteins, in nucleic acids, that comprise the hereditary material and life’s blueprint for all cells, and in many other organic and inorganic compounds. In addition, nitrogen comprises about 80% of the Earth's atmosphere.
Nitrogen is a component of amino acids and urea. Amino acids are the building blocks of all proteins. Protein comprise not only structural components such as muscle, tissue and organs, but also enzymes and hormones essential for the functioning of all living things.
Urea is a by product of protein digestion. We use the term "organic nitrogen" to describe a nitrogen compound that had its origin in living material. The nitrogen in protein and urea is organic nitrogen. Organic nitrogen can enter septic systems as bodily wastes, discarded food material, or as components of cleaning agents.
Therefore, the given statement is True.
