Abstract:

L-2-Hydroxytetradecanoic acid was recognized as a characteristic, although minor, constituent of the lipid A component of Salmonella lipopolysaccharides. The 2-hydroxy fatty acid was present in lipid A as an ester, probably bound to the hydroxyl group of some D-3-hydroxytetradecanoic acid residues. A survey of enterobacterial lipopolysaccharides showed that L-2-hydroxytetradecanoid acid was also present in Klebsiella and Serratia strains. It was absent, however, from lipopolysaccharides of other genera of the family including Escherichia, Shigella, Proteus, Enterobacter and Yersinia. This restricted distribution of the 2-hydroxy acid may be of significance for taxonomic studies of bacterial genera.
