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.
