Acrolein-conjugated lysine residues in proteins are present in human atherosclerotic lesions, and are detected in human low-density lipoprotein (LDL). These findings suggest that acrolein may contribute to macrophage foam cell formation and atherogenesis through modification of LDL. The purpose of

This work discusses the dependence of transition state geometries on the choice of quantum chemical optimization method for the extensively studied Diels-Alder reaction. Rather significant differences are observed between post-Hartree-Fock methods and (hybrid) density functional theory, where the latter predicts
