Bilayer thickness was computed from the average distance between phosphate planes (std. dev. < ± 0.02). The area per lipid (SD < ± 0.007) was computed as in reference (35). The variation of the electrostatic potential was calculated taking DEPE electrostatic potential as reference (795 mv). 2MOA, 2-methyloleic acid; 2MSA, 2-methylstearic acid; 2OHOA, 2-hydroxyoleic acid; 2OHSA, 2-hydroxystearic acid; cVcc, cis-vaccenic acid; DEPE, 1,2-dielaidoyl-sn-glycero-3-phosphoethanolamine; EA, elaidic acid; FA, fatty acid; OA, oleic acid; PeA, palmitelaidic acid; PoA, palmitoleic acid; SA, stearic acid.
