MS000020: Pseudaminic Acid Pack Size:100 μg 27 / An α-D-N-acetylgalactosamine (α-D-GalNAc)C13H22N2O8 334. 32 Pseudaminic acid (Pse, 5,7 diacetamido 3,5,7,9 tetradeoxy L glycero L manno nonulosonic acid) is a bacterial nine carbon nonulosonic acid structurally related to sialic acid (Neu5Ac) but found exclusively in prokaryotes, where it caps surface glycans, flagellins, and lipopolysaccharides of Gram negative pathogens such as Campylobacter, Helicobacter, Pseudomonas, and Acinetobacter. As a non mammalian sialic acid analog, pseudaminic
