Structures of the o-specific polysaccharide chains of pectinatus cerevisiiphilus and pectinatus frisingensis lipopolysaccharides
Senchenkova, Sof'ya N.; Shashkov, Alexander S.; Moran, Antony P.; Helander, Ilkka M.; Knirel, Yuriy A. (Wiley-Blackwell, 1995-09-01)Mild acid hydrolysis of the smooth-type lipopolysaccharide (LPS) of Pectinatus frisingensis afforded no polysaccharide but monomeric 6-deoxy-L-altrose (L-6dAIt) which was identified by anion-exchange chromatography in ...
