Abstract
FTIR spectroscopy has been employed in order to investigate alpha-toco pherol (alpha-T) and alpha-tocopheryl acetate (alpha-TA) induced effec ts on the molecular organization of dimyristoyl-L-alpha-phosphatidylch oline (DMPC) bilayers, at various temperatures and concentrations. It was concluded that alpha-T interacts much more strongly than alpha-TA, indicating that alpha-T has a more polar location in the membrane tha n alpha-TA. The observed changes in the carbonyl and phosphate group v ibrational modes of DMPC on addition of alpha-T or alpha-TA are discus sed. (C) 1997 Elsevier Science B.V.
