Nitroso compounds present in stool do not induce nitrosamine formation, because stool has neutral pH. [7] [8] Stomach acid catalyzes nitrosamine compound formation and is the main location of the reaction during digestion. [9] The formation process is inhibited when amine concentration is low (e.g. a low-protein diet or no fermented food).

Generally, people should not be exposed to a lifetime risk of cancer exceeding 1 in 100,000 from nitrosamines in their medicines. [12] EU regulators first became aware of nitrosamines in medicines in mid-2018, and took regulatory actions, including recalling medicines and stopping the use of active substances from certain manufacturers.

An alternative possible formation of diazonium and carbenium ions is through the enzymatic reaction of nitrosamines. [ 5 ] Typical accompanying symptoms during the medical cancer treatment via N -nitroso ureas are the impairment of bone marrow (damage of the stem cell compartment), lymphatic tissue and the gastrointestinal tract.
Cats on a vegan diet can develop abnormally alkaline (high pH) urine as most commonly used plant-based proteins are more alkaline than the meat-based foods which cats have evolved to eat. When the urine becomes too alkaline (pH >7), there is an increased risk of formation of struvite (also known as magnesium ammonium phosphate) bladder crystals ...
Among the tobacco-specific nitrosamines, nicotine-derived nitrosamine ketone (NNK) and N-nitrosonornicotine (NNN) are the most carcinogenic. [1] Others include N ′-nitrosoanatabine (NAT) and N-nitrosoanabasine (NAB). NNK and its metabolite 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) are potent systemic lung carcinogens in rats ...

Indeed, (meta)stable nitrosation products (alkyl nitrites or nitrosamines) can also nitrosate under such conditions; and the equilibria can be driven in any desired direction. Absent a driving force, thionitrosos form out of nitrosamines, which form out of nitrite esters, which form out of nitrous acid. [3]
