Figure 3.

Doughnut plot displaying the frequency of the occurrence of multiply unsaturated GPL acyl chains by sample. For example, acyl chain 18:2 was the most common unsaturated acyl chain because it was identified in 8 of the 12 investigated bacterial extract samples, whereas acyl chain 20:4 was identified in only 1 of the 12 bacterial extracts.
