Insect species can have up to nineteen different recognition proteins for this substance; those receptors are divided into hard and soft transcripts. Monomers of this molecule are assembled in the cytosol where they are attached to a carrier known as bactoprenol. A pseudo- version of this compound can render ineffective a cell's lysozyme; the lysozyme degrades the normal variety. Its structure consists of alternating units of N-acetylglucosamine and N-acetylmuramic acid liked by beta one four glycosidic bonds. This substance is dehydrated by alcohol, then traps insoluble (*) crystal violet-iodine complexes in the usual assay for detecting it; it is surrounded by a lipopolysaccharide coat in organisms negative for that technique. FTP, name this substance that makes up the majority of the cell wall in Gram-positive bacteria.
