Abstract
Sterols are a major component of cell membranes among all biological systems including bacteria, plant, fungi, and mammals. While the essential carbon skeleton found in all sterol-like structures is the sterane (cyclopentanoperhydrophenanthrenes) ring, there are minor variations which make each structure unique. These include hydroxylations, methylations, ketone groups, double bonds, etc. These structures play specific roles in the biological membranes. Earlier, sterols could only be detected using traditional methods like thin-layer chromatography or UV–vis spectrophotometry. However, these techniques are unable to accurately differentiate between these closely related sterol structures. Therefore, it becomes essential to develop new and sensitive methods for accurate quantification of sterols. In the last few decades, research on gas chromatography–mass spectrometry (GCMS)-based sterol structure determination and quantification has been on the rise. In this chapter, we have discussed some basic background of GCMS and its application in the absolute quantification of sterols using some examples.
