Murein, another name for peptidoglycan, is a polymer made of amino acids with a carbohydrate backbone.

Here, We Will Learn More About The Features, Cell Structure, And Gram Staining Procedure.

The lipopolysaccharide component acts as a virulence factor and causes disease in animals. More virulence factors are harbored in the periplasmic space between the outer membrane and the plasma. The cell envelope has 3 layers including, a unique outer membrane, a thin peptidoglycan layer, and the cytoplasmic membrane.

They Have Thick Cell Walls.
