  • Title: [Structural stabilization of lipids and visual pigment rhodopsin in the photoreceptor membrane by vitamin E].
    Author: Tiurin VA, Korol'kov SN, Berman AL, Kagan VE.
    Journal: Biull Eksp Biol Med; 1987 Oct; 104(10):391-4. PubMed ID: 2823926.
    Abstract:
    Interaction of alpha-tocopherol with free fatty acids in bovine retinal photoreceptor membranes was studied using ESR spin-probe technique and measurements of rhodopsin thermal denaturation rates. Exogenous alpha-tocopherol incorporated into photoreceptor membranes prevented thermal destabilization of rhodopsin caused by free fatty acids. The efficiency of the stabilizing action of alpha-tocopherol directly depended both on the chain length and the degree of fatty acid unsaturation.
