Abstract

Glycosaminoglycans (GAGs), particularly chondroitin sulfate (CS) and dermatan sulfate (DS), regulate brain processes through specific sulfation motifs. We report the first application of ion mobility spectrometry (IMS) mass spectrometry (MS) to neural GAG analysis. CS/DS octamers from mouse brain were profiled, revealing separation by sulfation content and glucuronic acid type. Eighteen distinct DS-rich domains were identified, including rare under- and oversulfated motifs. IMS MS/MS further resolved isomers and uncovered unusual trisulfated and pentasulfated structures. This approach advances brain glycosaminoglycomics and highlights novel, potentially bioactive CS/DS domains.
