For this purpose synthetic triacylglycerols of known structure were converted to hydroperoxides, hydroxides, epoxides, and core aldehydes and their dinitrophenylhydrazones by published procedures. The oxotriacylglycerols were resolved by normal\u2010phase thin\u2010layer chromatography and reverse\u2010phase HPLC, and the identities of the oxotriacylglycerols confirmed by LC\/ES\/MS. Elution factors of oxotriacylglycerols were determined in relation to a homologous series of saturated triacylglycerols, ranging from 24 to 54 acylcarbons, and analyzed by reverse\u2010phase HPLC, using a gradient of 20\u201380% isopropanol in methanol as eluting solvent and an evaporative light\u2010scattering detector. It was shown that the elution times varied with the nature of the functional group and its regiolocation in the triacylglycerol molecule. A total of 31 incremental elution factors were calculated from chromatography of 33 oxygenated and nonoxygenated triacylglycerol species, ranging in carbon number from 36 to 54 and in double\u2010bond number from 0 to 6.<\/jats:p>","DOI":"10.1007\/s11745-997-0155-4","type":"journal-article","created":{"date-parts":[[2006,11,13]],"date-time":"2006-11-13T13:03:16Z","timestamp":1163422996000},"page":"1211-1218","source":"Crossref","is-referenced-by-count":51,"title":["Elution factors of synthetic oxotriacylglycerols as an aid in identification of peroxidized natural triacylglycerols by reverse\u2010phase high\u2010performance liquid chromatography with electrospray mass spectrometry"],"prefix":"10.1002","volume":"32","author":[{"given":"Olli","family":"Sj\u00f6vall","sequence":"first","affiliation":[{"name":"Department of Biochemistry and Food Chemistry University of Turku Turku FIN\u201020014 Finland"},{"name":"Banting and Best Department of Medical Research University of Toronto, Charles H.
