what is a peptidoglycan? what is it made of?

Expert Solution

Peptidoglycan is basically a polysaccharide which is made up of N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM) which are derivatives of glucose. The amino acids i.e. L-alanine, D-glutamine, L-lysine or meso-diaminopimelic acid (DPA), and D-alanine cross links the peptidoglycan chains.

Both gram positive and gram negative bacterial cell walls contain peptidoglycan.

Penicillin is an antibiotic that inhibits peptidoglycan synthesis. Based on your results and knowledge of cell envelope differences, would penicillin be more effective against S. aureus (purple) or E. coli (red)? Explain your rationale.

Many antibiotics work by attacking various stages in the production of peptidoglycan in the cell wall of bacteria. Bacteria and Archaea are both prokaryotes that possess a cell wall. Yet antibiotics such as penicillin disrupts the cell wall of susceptible bacteria but generally do not affect Archaea at all. Why?
