Acrylamide is a probable human carcinogen that is neurotoxic to both humans and animals. It is known to be formed during cooking of foods at temperatures higher than 120 °C. The present study demonstrates that acrylamide can also be formed at physiological conditions (37 °C, pH 7.4) when asparagine is incubated in the presence of hydrogen peroxide (H2O2). The formation of acrylamide under these conditions is dependent on the incubation time and the concentration of H2O2. Thus, the results raise the question of the possible endogenous formation of acrylamide in pathological conditions that are associated with long-term oxidative stress. Further studies are therefore warranted to clarify the possible endogenous formation of acrylamide and its significance in chronic conditions that are known to be associated with oxidative stress.
