Sialic acid O-acetylation patterns and glycosidic linkage type determination by ion mobility-mass spectrometry.O-acetylation is a common modification of sialic acids that has been implicated in a multitude of biological and disease processes.  Here, we describe a drift tube ion mobility-mass spectrometry approach that can elucidate exact O-acetylation patterns as well as glycosidic linkage types of sialosides isolated from complex biological samples.
