WebStandards were non-radiolabelled. Ceramides were measured by means of LC (C8 column) and QTOF MS in positive ion mode. Ceramide C19 (non-radiolabelled) was used as IS. Ceramides were identified based on exact masses (m/z) followed by fragmentation of the target ion. Normalization was conducted to IS and samples’ protein concentration. WebA two-dimensional (2D) hydrophilic interaction liquid chromatography (HILIC) and reverse-phase (RP) liquid chromatography (LC) system coupled with triple-quadrupole mass spectrometry (MS) was developed to comprehensively profile ceramides and phosphatidylcholine in extracted biological samples. Brie … codeine withdrawal migraine Ceramide phosphoethanolamine (CPE) is a sphingolipid consisted of a ceramide and a phosphoethanolamine head group. CPE is the major sphingolipid class in some invertebrates such as members of Drosophila. In contrast, mammalian cells contain only small amounts of CPE.
