Résumé : A multidisciplinary approach demonstrates the existence of a specific interaction between the cationic form of atrazin (a selective herbicide) and sulfoquinovosyldiacylglycerol, a negatively charged lipid of the thylakoid membrane. From surface potential measurements (carried out on monolayers and liposomes) we calculated an association constant of about 106 M-1. © 1993.
