A kinetic model was constructed from our datasets to describe lipid oxidation reactions (in Table ) by first (R.1 and R.4) and second order reactions. The reactivity of AAPH and BODIPY in the system was accounted for by reactions R.8 and R.9 (Table ) in the kinetic model. To estimate the impact of changes in D32 on the formation of lipid oxidation products, we varied D32 with deviations of 𝜎. The concentration over time of the compounds with D32 was denoted as [C]. Then, with D32 ± 𝜎, the varied concentration denoted as [𝐶 ̃] can be calculated as (see Supplementary materials).
