Figure 3: Oxidation of EPA, DHA, and OA in CaCo-2 cells. The cells plated on filter membranes and cultured for 21 days were incubated in serum-free DME medium containing 400 μm [l-14C]OA, [l-14C]EPA, or [l-14C]DHA for 36 h. (a) CO2 was collected and acid-soluble radioactivity in the incubation medium was measured as described in Section 2. (b) The sum of CO2 and acid-soluble radioactivity as % of total added radioactivity is given. Data are expressed as mean ± SD of 6 different experiments. Means without a common letter differ, .
