 CHAPTER 3 - CARBOHYDRATES/GLYCANS

B:  More Complex Carbohydrates

 03/15/16

Learning Goals/Objectives for Chapter 3B:  After class and this reading, students will be able to

  • state the differences between the homopolysaccharides glycogen, starch cellulose, and chitin and those with dissacharide repeat units (glycosoaminoglycans)
  • draw cartoon models of complex oligosaccharides such as peptidoglycans of bacterial cell walls, N and O linked glycoproteins, and proteoglycans showing the linkage of protein and CHO
  • describe the role of protein and cell surface CHO in binding and biological function
  • given diagrams of leukocyte and endothelial cells interactions, describe the role of selectins, selectin ligands, integrins and cellular adhesion molecules in immune cell/blood vessel interactions.

This chapter on complex carbohydrates (glycans/glycoconjugates) will review those features that are deemed especially important for a one semester course dealing with structure and function of biomolecules.
