Abstract O-acetylation is a common modification of sialic acids that has been implicated in a multitude of biological and disease processes. A lack of analytical methods that can determine exact structures of sialic acid variants is a hurdle to determine roles of distinct O-acetylated sialosides. Here. we describe a drift tube ion mobility-mass spectrometry approach that can elucidate... https://unitedssports.shop/product-category/bike-units-adult-trike/
