Produktinformation
Cholesterol-d6 is an analytical method for measuring the concentration of cholesterol in biological samples. The experimental model used to determine the amount of cholesterol in a sample is based on the chemical ionization of desmosterol, a precursor molecule found in animal tissues. The matrix effect is defined as the relative proportion of the number of molecules that are ionized by a specific ionizing agent. Cholesterol-d6 is typically analyzed using gas chromatography and mass spectroscopy (GC/MS) with a chemical ionization source. In order to measure cholesterol levels in serum, plasma, or other body fluids, it is necessary to prepare the sample by separating it into its lipid and water components through solvent extraction and evaporation. This process can be done using various solvents including chloroform, ethyl ether, hexane, methanol, or petroleum ether. Cholesterol-d6 has been shown to have pharmacokinetic properties that are similar to those of 17β-
