Mechanismus der Reaktion von Invertseifen mit isolierten Zellen

Summary Reaction equilibria were established between an invert soap on the one side and carbon, lecithin, erythrocytes and yeast cells on the other side. From the parallelism of the invert soap-lecithin and the invert soap-erythrocytes curves a specific reaction of the invert soap with the lipoids of the erythrocytes may be concluded, whereas the invert soap-yeast cells curves yield a pure adsorption isotherm corresponding to the invert soap-carbon curve.

Obtention d'un dérivé du sclaréol à partir de l'ambréine

Summary One of the products of the chromic acid oxidation of the animal triterpene ambreine (V) has been identified with the lactone C₁₆H₂₆O₂ (III) whichRuzicka and coll. had isolated by oxidation of the plant diterpene sclareol (II). This identification confirms recent findings of the authors and ofRuzicka, Dürst andJeger and shows that the hydroxyle of ambreine (V) is at the same place as the hydroxyle of sclareol which is attached to the perhydronaphtalene ring.
