Interaction of tea catechins with lipid bilayers has been investigated with liposome systems. Tea catechins are classified into cis-type and trans-type from the configuration of the two hydrogens at the 2 and 3 positions on the C-ring. The amount of trans-type catechins incorporated into liposomes was less than that of the respective cis-type catechins. Furthermore, the order of the partition coefficients of catechins in an n-octanol/PBS system is the same as that of the amount incorporated into liposomes. These results indicate that in addition to the number of hydroxyl groups on the B-ring and the presence of the galloyl moiety, the stereochemical structure of the C-ring also governs the hydrophobicity and the affinity for lipid bilayers. Trans-type catechins with the galloyl moiety were located on the surface of the lipid bilayer, as well as cis-type catechins with the galloyl moiety, and perturbed the membrane structure. These different stereochemical structures should influence the affinity for lipid bilayers, the alteraction of membrane structures, and the difference in the order of the biological activities.
