Biological Functions of Glycans

This chapter provides an overview of the biological functions of glycans in three broad categories: structural and modulatory roles, including nutrient storage and sequestration; specific recognition—most commonly by glycan-binding proteins of intrinsic or extrinsic origin; and molecular mimicry of host glycans. The chapter then presents some general principles for understanding and further exploring biological functions of glycans. For details, see the sources cited and the other chapters in this book.
