The most abundant pool of nitrogen in the cell is in the nitrogenous bases of DNA and RNA (adedine, cytosine, guanine, thymidine, and uracil). Of course these same bases would be found in nucleosides and nucleotides and in other compounds such as NAD and FAD. Nitric oxide is a short lived signaling molecule. There are other molecules as well, but these are the main molecules that contain nitrogen.

You have to eat something! People have asked me this question as well and I think it's a bit sarcastic and disrespectful. I never badger my friends about what they eat, why should they? Plants don't have brains. No emotions, nervous system, therefore no feeling. They're only alive in the sense that they breathe (in a way) and grow. A plant won't play with you like a pig will. Plants don't have relationships with their families.

Found in many plants as NO2 is a nitrogen fertilizer. In nature it is created by lightening strikes.

What do you mean? It is in our cells, our DNA...
