L'acide N‐glycolyl‐muramique, constituant des parois de Mycobacterium smegmatis: Identification par spectrometrie de masse

Abstract
The repeating disaccharide unit of the mucopeptide of the cell wall of Mycobacterium smegmatis contains N-acetyl-glucosamine linked to N-glycolyl-muramic acid. This first identification of N-glycolyl-muramic acid as a natural product has been performed by mass spectrometry of the permethylated disaccharide. N-glycolyl muramic acid has been synthesized: the natural and synthetic products are identical.
