Structural studies of the capsular polysaccharide from Haemophilus pleuropneumoniae serotype 1. 1986

E Altman, and J R Brisson, and M B Perry

The capsular polysaccharide of Haemophilus pleuropneumoniae serotype 1 (ATCC 27088) was found to be a teichoic acid type polysaccharide of a repeating disaccharide unit composed of 2-acetamido-2-deoxy-D-glucose and D-galactose units. By composition analysis, methylation, partial hydrolysis, dephosphorylation, and one- and two-dimensional 500-MHz proton nuclear magnetic resonance experiments, together with 13C nuclear magnetic resonance studies, it was concluded that the capsular polysaccharide is a high molecular weight linear polymer having the structure: (Formula: see text)

UI	MeSH Term	Description	Entries
D008745	Methylation	Addition of methyl groups. In histo-chemistry methylation is used to esterify carboxyl groups and remove sulfate groups by treating tissue sections with hot methanol in the presence of hydrochloric acid. (From Stedman, 25th ed)	Methylations
D009682	Magnetic Resonance Spectroscopy	Spectroscopic method of measuring the magnetic moment of elementary particles such as atomic nuclei, protons or electrons. It is employed in clinical applications such as NMR Tomography (MAGNETIC RESONANCE IMAGING).

D002621	Chemistry	A basic science concerned with the composition, structure, and properties of matter; and the reactions that occur between substances and the associated energy exchange.
D005690	Galactose	An aldohexose that occurs naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins. Deficiency of galactosyl-1-phosphate uridyltransferase (GALACTOSE-1-PHOSPHATE URIDYL-TRANSFERASE DEFICIENCY DISEASE) causes an error in galactose metabolism called GALACTOSEMIA, resulting in elevations of galactose in the blood.
