Chemical Information
FooDB NameLactucin
DescriptionLactucin belongs to the class of organic compounds known as gamma butyrolactones. Gamma butyrolactones are compounds containing a gamma butyrolactone moiety, which consists of an aliphatic five-member ring with four carbon atoms, one oxygen atom, and bears a ketone group on the carbon adjacent to the oxygen atom. Lactucin is an extremely weak basic (essentially neutral) compound (based on its pKa). Lactucin has been detected, but not quantified in, several different foods, such as herbs and spices, lettuces, chicories, endives, and green vegetables. This could make lactucin a potential biomarker for the consumption of these foods.
