It was concluded that α-T interacts much more strongly than α-TA, indicating that α-T has a more polar location in the membrane than α-TA. The observed changes in the carbonyl and phosphate group vibrational modes of DMPC on addition of α-T or α-TA are discusseden-USα-Tocopherolα-Tocopheryl acetateDimyristoyl-l-α-phosphatidylcholineDMPCBilayersFTIRArticle
