What macromolecules contain nitrogen

Nitrogen can be found in living organisms as a gas (in cells), and/or in oxidized or reduced form (8). Nitrogen in the reduced form is the major component of the three most important biological macromolecular structures: (i) proteins/polypeptides, (ii) DNA and RNA, and (iii) polymers of amino sugars.
