摘要: The effects of embedding up to 60 mol% α-tocopherol (α-Toc) on the morphology and structure egg phosphatidylcholine (PC) membrane were studied using spectroscopic techniques. resulting vesicles subjected turbidometric dynamic light scattering measurements evaluate their size distribution. α-Toc intrinsic fluorescence its quenching was used estimate tocopherol position in membrane. Optical microscopy visualize morphological changes during inclusion into 2 mg/ml PC incorporation 15 molecules is accompanied by a linear increase intensity simultaneous formation larger, multilamellar vesicles. Increasing concentration above 20 induced structural leading disappearance micrometer-sized small unilamellar ranging from 30 120 nm, mixed micelles non-lamellar structures.
