Bacterial cell wall comparison. Computer artwork comparing the structure of the cell wall from a gram-negative bacterium (left) with that of a gram-positive bacterium (right). Both forms have a cell membrane consisting of a phospholipid bilayer (blue), and then a layer of peptidoglycan (murein, red) on the outside of this. The gram-negative cell wall has a thin peptidoglycan layer and then a second membrane (orange), whereas the gram-positive one lacks the second membrane but has a much thicker peptidoglycan layer.
