Abstract
The structure of the lipopolysaccharide from Salmonella friedenau T1 form has been investigated. The T1‐specific chains are composed of almost equal amounts of β‐d‐ribofuranose and β‐d‐galactofuranose residues. The former are linked to the 2‐position, the latter to the 3‐position or, to a smaller extent, to the 6‐position. A low percentage of branching, through β‐d‐galactofuranose residues, substituted in the 3‐ and 6‐position, is demonstrated. The core region of the T1 lipopolysaccharide seems to have the same general structure as that of other Salmonella lipopolysaccharides.
