Differential binding of vitamin E to sarcoplasmic reticulum from fast and slow muscles of the rabbit

Summary The distribution of [³H]-tocopherol between the intracellular membranes of fast white and slow red muscles was studied in vivo. In vitro experiments confirmed a higher incorporation of the vitamin into the reconstructed sarcoplasmic reticulum membranes from slow muscle.This work was supported by funds from the Consiglio Nazionale delle Ricerche to the C.S. Biologia e Fisiopatologia Muscolare and to the Istituto di Patologia Generale, Università di Bologna, and in part by a grant from the Muscular Dystrophy Association to Prof. Aloisi.
