The results suggest that the effect of alpha-tocopherol in lowering the phase-transition temperature depends on its hydrophobic side chain, and that its effect in decreasing the membrane fluidity above thephase-transitions temperature depends in part on its hydrophylic chroman ring portion.

The 1O2 quenching rate constants (kQ) of α-tocopherol (α-Toc) and carotenoids such as β-carotene, astaxanthin, canthaxanthin, and lycopene in liposomes were determined in light of the localization of…

The ratio of the antioxidant activity of β‐Car to that of α‐Toc was more in EtOH solution than in liposomes, and was well correlated with the ratio of their 1O2 scavenging rate constants.
