Background:

  • Carbohydrate modifications, including epimerization and acetylation, occur after backbone formation.
  • These post-glycosylational modifications (PGMs) increase structural complexity and biological regulatory capacity.
  • Understanding PGMs is vital for glycobiology and developing novel carbohydrate-based therapeutics.

Purpose of the Study:

  • To review classes of carbohydrates with PGMs and their applications.
  • To highlight recent advances in synthesizing these complex carbohydrate structures.
  • To emphasize the importance of synthetic PGMs in structure-activity relationship studies.

Main Methods:

  • Review of chemical synthesis strategies for PGMs.
  • Exploration of enzymatic and chemoenzymatic approaches for PGM synthesis.
