Definition of 'nitrogen'. nitrogen (naÉªtrÉdÊÉn ) Nitrogen is a colourless element that has no smell and is usually found as a gas. It forms about 78% of the earth's atmosphere, and is found in all living things.
Nitrogen is an essential part of amino acids and nucleic acids both of which are essential to all life. Specific bacteria (e.g. Rhizobium trifolium) possess nitrogenase enzymes which can fix atmospheric nitrogen (see nitrogen fixation) into a form (ammonium ion) which is chemically useful to higher organisms.
