For 10 points, name this compound that makes up the cell wall of bacteria.
Dipeptide fragments of this compound are recognized by the NOD2 receptor. One drug that inhibits the synthesis of this compound has the horrifying side effect of Red Man Syndrome. A transglycosylase is responsible for crosslinking the subunits of this compound in the final step of its synthesis, after its subunits are transported by a pyrophosphate-containing lipid called bactoprenol. This compound, which is a complex polymer of D-amino acids, N-acetyl-glucosamine, and N-acetyl-muramic acid, makes up about 90% of the dry weight of gram-positive organisms. Beta-lactams like penicillin inhibit the synthesis of this compound, which is also broken down by lysozyme in tears. For 10 points, name this compound that makes up the cell wall of bacteria.
