Structural and Serological Analysis of Citrobacter‐036‐Specific Polvsaccharide, the Homopolymer of (βl→ 2)‐Linked 4‐Deoxy‐d‐arabinohexopyranosyl Units

Abstract
The chemical structure of the O‐specific polysaccharide of Citrobacter 036 lipopolysaccharide has been estab‐ lished by methylation analysis using gas‐liquid chromatography and mass spectrometry. This polysaccharide is a linear homopolymer composed of (β1 →2)‐linked 4‐deoxy‐d‐arahinohexopyranosyl residues.
