Abstract : Vitamins E, C and polyphenols (flavonoids and non-flavonoids) are major natural antioxidants capable of preventing damage generated by oxidative stress. Here we show the capacity of these antioxidants to form non-covalent association within lipid bilayers close to the membrane/cytosol interface. Antioxidant regeneration is significantly enhanced in these complexes.

Keywords : alpha tocopherol antioxidant ascorbic acid flavonoid quercetin controlled study cytosol drug potentiation enthalpy lipid bilayer lipophilicity membrane oxidative stress simulation
