Humans are ubiquitously exposed to crotonaldehyde to a strongly varying extent, in particular, via food and alcoholic beverages. Like other alpha,beta-unsaturated carbonyl compounds, crotonaldehyde forms 1,N(2)-propanodeoxyguanosine adducts and is genotoxic, mutagenic, and carcinogenic. This study

Crotonaldehyde and 2-hexenal are bifunctional compounds that form 1,N2-propanodeoxyguanosine adducts and are mutagenic and genotoxic; crotonaldehyde is carcinogenic. Analysis of the mutations resulting from crotonaldehyde-induced DNA damage revealed the importance of deoxyguanosine adducts. Humans

Crotonaldehyde is a genotoxic, mutagenic and carcinogenic alpha,beta-unsaturated carbonyl compound which forms 1,N2-propanodeoxyguanosine adducts. Humans are exposed to this compound at work places, and from tobacco smoke and air pollution, but also from food and beverages. Therefore crotonaldehyde
