The fatty acid proportions present in the LPS isolated from B. fragilis, B. thetaiotaomicron, and P. gingivalis 1626 given as a percent of the total identified fatty acidsa.
| B. fragilis | B. thetaiotaomicron | P. gingivalis 1626 | |
|---|---|---|---|
| Iso-C15 | 19.7 % | 8.5 % | 14.1 % |
| Anteiso-C15 | 6.6 % | 20.4 % | 12.5 % |
| C16 | 1.9 % | 3.2 % | 24.1 % |
| 3-OH-C15 | 0.0 % | 0.0 % | 0.0 % |
| 3-OH-C16 | 31.6 % | 40.8 % | 8.0 % |
| 3-OH-C17 | 40.3 % | 27.1 % | 41.4 % |

The percents were calculated as follows: The amount of each fatty acid was determined by dividing the area (in mm2) under the GC trace by the amount of dry weight bacteria (in mg) used to isolate the LPS. These quotients were added, and the resulting sum (total area/mg) was set equivalent to 100%. Therefore, each fatty acid (measured in area/mg) could be calculated as a percent of the total area/mg. The results are representative of two independent determinations.
