      ELV-N34, (Systematic Name:(16Z,19Z,22R,23E,25E,27Z,29S,31Z)-22,29-dihydroxydotetratriaconta-16,19,23,25, 27,31-hexaenoic acid) represents a novel class of lipid mediators biosynthesized in human retinal pigment epithelial (RPE) cells that are oxygenated derivatives of very long-chain polyunsaturated fatty acids (VLC-PUFAs,n-3). These mediators have been named elovanoids (ELV) and are necessary for neuroprotective signaling for photoreceptor cell integrity. Photoreceptor cells express the elongase enzyme ELOVL4 which catalyzes the biosynthesis of elovanoids from 22:6 fatty acids derived from DHA or EPA.

In plants, glycerolipid biosynthesis in chloroplasts has long been termed the "prokaryotic pathway", and it produces galactosyldiacylglycerols and phosphatidylglycerol with C18 acids in position sn-1 and C16 acids in position sn-2. This pattern is seen in cyanobacteria and it has been assumed that the similarity was a consequence of endosymbiosis during evolution. A new study demonstrates that this is not true …
