The Cell Wall and Surface Structures This lecture will focus on the structures that coat prokaryotic cells and which are outside of the cytoplasmic membrane. The particular focus will be on how these structures were revealed and how their function was determined. This first reading focuses on peptidoglycan and its functional equivalents.
