CHOLESTEROL-ESTERASE COLOUR SUBSTRATE
A cholesterol esterase substrate of the general formula I in which A is an alkylene or alkenylene group with 1 to 20 C atoms, Chol is the 3-cholesterol radical, X is the radical of an aromatic hydroxy or thiol compound and Y is -S- or -O-, is described. For the optical determination of cholesterol e...

description | A cholesterol esterase substrate of the general formula I in which A is an alkylene or alkenylene group with 1 to 20 C atoms, Chol is the 3-cholesterol radical, X is the radical of an aromatic hydroxy or thiol compound and Y is -S- or -O-, is described. For the optical determination of cholesterol esterase, a substrate of this type is exposed to the action of a sample containing cholesterol esterase and the amount of liberated aromatic hydroxy or thiol compound is determined directly or optically, using the colour formed therefrom after coupling to a suitable chromogen. |
