Upper panels: raw data from ITC experiments. Each peak corresponds to a single injection of 10 μL of a PLPC LUV suspension [5 mM for (A) and (B), 1 mM for (C)] into a solution containing (A) 500 μM nonanoic acid, (B) 75 μM sarmentine and (C) 75 μM sorgoleone at 26°C. LUV suspension and herbicides solutions were buffered at pH 7 with TRIS – HCl. Lower panels: cumulative heats of binding (Σδhi) as a function of the lipid concentration in the cell (C0L). Solid line corresponds to the best fit using the Eq. 4.
