Quick Answer. According to HowStuffWorks, nitrogen is important to humans and all other living organisms because it is an important component of amino acids. Humans use amino acids to build proteins that form the building blocks of many biological tissues. Continue Reading.
Nitrogenmakes up almost four fifths of the air we breathe, but being unreactive is not used in respiration at all - we simply breathe the nitrogen back out again, unchanged. However, nitrogen is essential for the growth of most living things, and is found as a vital ingredient of proteins. Under normal conditions nitrogen is a gas, composed of a simple diatomic molecule of formula N 2. It is colourless and odourless, but unlike its partner in the atmosphere, oxygen, forms triple bonds . This makes it one of the strongest chemical bonds known (DH dissociation = 944.7 kJ mol-1), and this is primarily responsible for the inertness of N 2.
