Die Struktur des Ubichinons aus Schweineherzen

Abstract

Abstract The isolation in pure form of the ubiquinone from pig heart is described. From 750 kg raw material 37 g of pure crystalline material could be obtained. Its structure has been established as that of a 2,3‐dimethoxy‐5‐methyl‐benzoquinone derivative with a vitamin‐K 2 ‐like isoprenoid side chain of 50 carbon atoms (I). It is proposed to name this compound ubiquinone(50).
