L-Ala-D-Glu-m-DAP-D-Ala-D-Ala

L-Ala-D-Glu-m-DAP-D-Ala-D-Ala is an essential structural peptide of peptidoglycan in Gram-negative bacteria. Peptidoglycan forms a network structure composed of repeating units of N-acetylglucosamine (GlcNAc) and N-acetylmuramic acid (MurNAc) that are cross-linked by L-Ala-D-Glu-m-DAP-D-Ala-D-Ala. This compound can be utilized in studies related to bacterial metabolism labeling.
