Summary: N-Acetylglucosamine (GlcNAc) is an essential monosaccharide required in almost all organisms. Fluorescent labeling of the peptidoglycan (PG) on N-acetylglucosamine has been poorly explored. Here. we report on the labeling of the PG with a bioorthogonal handle on the GlcNAc. https://www.bekindtopets.com/great-pick-Nobivac-Feline-1-HCPCh-special-find/
