Which chemical is found in peptidoglycan? The outer leaflet found outside the thin peptidoglycan layer of Gram-negative cell wall made of lipopolysaccharide (LPS) Gram-negative bacteria each have four of this in its basal body,anchor the flagellum to the cell membrane The structural part of a bacterial flagellum is composed of flagellin The union of lipid with sugar in the outer membrane of Gram-negative cell walls The channels through both leaflets of the outer membrane of Gram-negative cell wall A medical student is examining some Gram stained specimens. She notes that some prokaryotic cells appear purple under the microscope. She concludes they are D. The periplasmic space E. Capsule F. Integral proteins called porins G. Gram-positive bacteria H. Peptidoglycan I. The rings J. two N-acetylmuramic acid molecules K. bacterial flagella L. Taxis M. Mycolic acid N. Nucleus O. Lipid A P. Filament Q. N-acetylglucosamine R. Lipopolysaccharide
