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://safeersappliancers.shop/product-category/neff-n50-ki5872sf0g-integrated-70-30-fridge-freezer/
