Although itwas not particularly abundant, it is important to consider
the distribution of 20:5n−3 because of its widely recognized human
health benefits as the precursor to eicosanoids which are less proinflammatory
than those derived from the equivalent n−6 LC-PUFA,
20:4n−6 (Yates et al., 2014). The only lipid class that contained significant
amounts of 20:5n−3 was PE. In this lipid class, the ratio of
22:6n−3 to 20:5n−3 was 7.0, similar to the ratio of 7.9 found for the
total lipid. Again this suggests selective incorporation of 22:6n−3 into
the cellular lipids and/or selective metabolism of 20:5n−3.
