Addressing the glycan complexity by using mass spectrometry: In the pursuit of decoding glycologic

Introduction Nucleotides, amino acids, carbohydrates, and lipids are the essential elementary molecular units constituting biological systems. Among these, polymers and/or their conjugates directly drive biological events. Glycans, the oligomers of carbohydrates, linked to lipids and proteins, play pivotal roles in many biological phenomena. Since glycan synthesis is nontemplate dependent, the structural
