In a sphingomyelin-enriched sample of polar lipids from bovine milk, molecular species of intact sphingomyelin were separated by normal-phase high-performance liquid chromatography and detected by mass spectrometry (MS) for structural information. First, by using electrospray with positive ionizatio
