The comparative formation of the heterocyclic aromatic amine 2 - amino - 1 - methyl - 6 - phenylimidazo [ 4 , 5 - b ] pyridine ( PhIP ) in both creatinine / phenylalanine ( CRN / Phe ) and creatinine / phenylalanine / 4 - oxo - 2 - nonenal ( CRN / Phe / ON ) systems was studied to analyse the ability of lipid - derived reactive carbonyls to promote PhIP formation .
