| Name: | Nitrogen |

| Description | Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78% by volume of Earth's atmosphere. Nitrogen occurs in all living organisms. In E. coli, nitrogen exists as a dissolved gas in the cell cytoplasm. E. coli is not able to "fix" nitrogen or readily incorporate it into metabolites. It is a constituent element of amino acids and therefore of proteins and nucleic acids (DNA and RNA). The characteristic odor of animal flesh decay is caused by nitrogen-containing long-chain amines, such as putrescine and cadaverine. Decay of organisms and their waste products may produce small amounts of nitrate, but most decay eventually returns nitrogen content to the atmosphere, as molecular nitrogen. The circulation of nitrogen from the atmosphere through organics and then back to the atmosphere is commonly referred to as the nitrogen cycle. |
