| Abstract: |
Oxysterols are oxygenated forms of cholesterol. This definition can, however, be expanded toinclude oxygenated derivatives of plant sterols and also of cholesterol precursors. Oxysterols areformed in the first steps of cholesterol metabolism and also from cholesterol by reactive oxygenspecies. Oxysterols were once thought of as simple intermediates, or side-products, in the conversionof cholesterol to hormonal steroids and bile acids, however, they have subsequently been shown to bebiologically active molecules in their own right. In this article we will discuss methods of oxysterolanalysis including "classical" gas chromatography - mass spectrometry (GC-MS) methods and morerecent liquid chromatography (LC)-MS methods. Our main focus, however, will be on analyticalmethods based on "charge-tagging" and LC-tandem mass spectrometry (MS/MS or MSn) which wehave developed over the last decade in our laboratory. Examples will be given of oxysterol analysis inbrain, cerebrospinal fluid (CSF) and blood. The advantages and disadvantages of the various methodsof oxysterol analysis will be discussed. |
