fatty acid analysis of the phospholipid and lipopolysaccharide fractions from cells grown with cerulenin , pentadecanoate , and oleate revealed that over 60 % of the native even-numbered fatty acids of the phospholipid fraction was substituted by the odd-numbered fatty acid , while no incorporation of either the pentadecanoate or oleate could be demonstrated in the lipid a moiety of the lipopolysaccharide .
