 (nī-trō′sə-mēn′, nī′trōs-ăm′ēn)
n.
The group, N2O, having a divalent nitrogen atom bonded to a nitrogen atom that is doubly bonded to an oxygen atom, or any of a series of organic compounds having two alkyl groups bonded to this group. Nitrosamines are present in various food products and are carcinogenic in laboratory animals.

[Latin nitrōsus, full of natron (from nitrum, natron; see niter) + amine.]
