This molecule can be detected by the nod2 protein, mutations of which are associated with Crohn's disease. These molecules are separated by polymerized teichoic acid. During its synthesis, racemase converts L-alanine to D-alanine, as this molecule unusually contains multiple D-amino acids. This molecule consists of alternating N-acetylglucosamine and N-acetylmuramic acid molecules. In one method, a structure mostly made from this material traps the dye crystal violet, while other structures without it is stained pink. For 10 points, name this macromolecule that comprises the cell walls of gram positive bacteria.
