What is peptidoglycan?
Quick Answer
Peptidoglycan is a strong mesh-like molecule that forms much of bacterial cell walls. It helps bacteria keep their shape and resist bursting.
The Full Story
Peptidoglycan is a polymer made of sugars and amino acids that forms a rigid layer outside the bacterial membrane. It gives many bacteria their shape and protects them from osmotic pressure. Gram-positive bacteria usually have a thick peptidoglycan layer, while Gram-negative bacteria have a thinner one plus an outer membrane. Many antibiotics, including penicillin, interfere with peptidoglycan synthesis.
