Glycosaminoglycan glycomics using mass spectrometry

Area of Science:

• Biochemistry
• Glycobiology
• Analytical Chemistry

Background:

• Sulfated glycosaminoglycans (GAGs) are essential for numerous physiological functions in animals.
• Understanding GAG biology is hindered by their inherent heterogeneity and complex expression patterns.
• Current knowledge lacks the structural detail required for establishing definitive GAG structure/function relationships.

Purpose of the Study:

• To review advancements in mass spectrometry-based glycomics for GAG analysis.
• To highlight the need for sensitive, high-throughput glycomics platforms.
• To facilitate a deeper understanding of GAG structure and function.

Main Methods:

• Review of mass spectrometry-based methodologies for GAG glycomics.
• Discussion of techniques including disaccharide analysis.
• Exploration of oligosaccharide profiling and tandem mass spectrometry sequencing.

Main Results:

• Mass spectrometry-based glycomics platforms are advancing.
• These platforms offer improved sensitivity, robustness, and throughput for GAG analysis.
• Progress in disaccharide analysis, oligosaccharide profiling, and MS/MS sequencing is detailed.

Conclusions:

• Mass spectrometry is a powerful tool for GAG glycomics.
• Enhanced analytical capabilities are crucial for deciphering GAG heterogeneity.
• Further development of these methods will advance our understanding of GAG biology and its implications.
