Introduction:

Peptidoglycan makes up a major portion of the cell wall of the Gram negative as well as the Gram-positive bacteria. The Gram-positive bacteria’s cell wall is found to be thicker in comparison to the Gram-negative bacteria and they also have much more peptidoglycan than that of the Gram-negative bacteria’s cell wall.
