What organic molecules contain phosphorus and nitrogen?
Nicotinamide adenine dinucleotide (NAD) is a coenzyme used in living cells comprising of a dinucleotide linked through phosphate group, with one nucleotide linked with an adenine base and the other with a nicotinamide base. Thus, it contains both phosphorus (P) and nitrogen (N).
Phosphatidylcholine, a class of phospholipids with choline as a head group is another illustrative example and form a major component of biological membranes.
Cyclophosphamide, a chemotherapeutic pro-drug is a significant synthetic organic molecule having both N and P.
