General description

Rate coefficients for the reaction of crotonaldehyde with chlorine atoms have been determined. Reaction of crotonaldehyde with DNA has been investigated.

Application

  • Crotonaldehyde (Cis and Trans): Discusses the production and properties of crotonaldehyde, including trans isomer, via aldol condensation of acetaldehyde and catalytic methods (Grant & Jenkins, 2015).
  • Modeling, simulation and analysis of a process for the production of crotonaldehyde: Analyzes the production of crotonaldehyde, highlighting the stereoisomeric forms, including trans-crotonaldehyde (Scheithauer et al., 2016).

Humans are exposed to acrolein and crotonaldehyde due to environmental pollution and endogenous lipid peroxidation. These aldehydes react with the 2'-deoxyguanosine moiety of DNA, forming the exocyclic 1,N2-propano-2'-deoxyguanosine adducts AdG and CdG. These adducts are mutagenic lesions, and they play
