Carbohydrates differ from other biological polymers, such as nucleic acids and proteins, in many ways. Most importantly, they have different functional groups that provide almost unlimited variations in their structures. Carbohydrates that are conjugated to proteins or lipids are termed glycoconjugates. They decorate the outer surface of mammalian cells. Their strategic location enables them to regulate many important biological processes, including fertilization, cell growth, cell-cell adhesion, cell-cell communication, development, immune defense, viral and parasitic infection, degradation of blood clots, inflammation etc. Furthermore, alterations in the synthesis or catabolism of cell-surface carbohydrates are associated with various pathological conditions, including malignant transformations and congenital and neurological disorders. Deciphering the enigmatic structures of carbohydrates and understanding their biosynthetic/catabolic pathways are critical for the development of carbohydrate-based therapeutics. In our lab, we are developing new tools to synthesize and characterize heparan sulfate structures (a special class of carbohydrate polymers) with a final goal to understand their biosynthetic and catabolic pathways, and their role in various physiological processes (axon guidance, regeneration, and learning and memory) and in human diseases (cancer, congenital defects, thrombosis, brain disease and Sanfilippo disease).
