Abstract

Abstract Translated from German Es wird ein Cholesterinesterasesubstrat der allgemeinen Formel I X - - A - - Y - Chol      I beschrieben, worin A eine Alkylen- oder Alkenylengruppe mit 1 bis 20 C-Atomen, Chol den 3-Cholesterinrest, X den Rest einer aromatischen Hydroxy- oder Thiolver­bindung und Y -S- oder -O- bedeuten. Zur optischen Bestimmung der Cholesterinesterase unter­wirft man ein solches Substrat der Einwirkung der cholesterinesterasehaltigen Probe und bestimmt die Menge der freigesetzten aromatischen Hydroxy- oder Thiolverbindung direkt oder, nach Kopplung mit einem geeigneten Chromogen, die daraus gebildete Farbe op­tisch. It becomes a cholesterol esterase substrate of the general formula I X - - A - - Y - Chol I described in what A is an alkylene or alkenylene group with 1 to 20 carbon atoms, chol is the 3-cholesterol residue, X is the residue of an aromatic hydroxy or thiol compound and Y is -S- or -O-. For the optical determination of cholesterol esterase, such a substrate is subjected to the action of the sample containing cholesterol esterase and the amount of aromatic hydroxy or thiol compound released is determined directly or, after coupling with a suitable chromogen, the color formed therefrom optically.
