recent studies of salmonella lipid a indicate that 3-hydroxytetradecanoic acid ( 3-oh-14:0 ) residues are directly linked to the glucosamine backbone and the nonhydroxylated fatty acids ( principally dodecanoic and tetradecanoic acids ) are esterified to the hydroxyl groups of some of the 3-oh-14:0 molecules .
