Chapter 13, Problem 3P

Summary Introduction

To examine: Whether the statement “All the glycoproteins and glycolipids in intracellular membranes have oligosaccharide chains facing the luminal side, and all those in the plasma membrane have oligosaccharide chains facing the outside of the cell” is true or false.

Introduction: Glycosylation is the addition of oligosaccharides that may modify the protein’s antigenic and functional properties. Proteins and lipids move through the Golgi stack in the cis-to-trans direction.
