From: Quantitative detection of free 24S-hydroxycholesterol, and 27-hydroxycholesterol from human serum
Identification and fragmentation of 24S or 27-hydroxycholesterol and 24(R/S)-hydroxycholesterol (d6). Mass spectra for A) identification (Q1 scan) and B) fragmentation (product ion scan) of a purified 24S or 27-hydroxycholesterol standard (420.3Â m/z), C) identification (Q1 scan) and D) fragmentation (product ion scan) of 24(R/S)-hydroxycholesterol (d6) (426.6Â m/z) in positive mode using API3000 mass spectrometer.
