TL;DR: Alkaline isomerization combined with ozonization-hydrogenation-GLC combined with these procedures was applied to determine the unusual double bond structures, and permits positional identification of an internal double bond.
Abstract: Arachidonic and related fatty acids which normally are found only in animals or microorganisms have been isolated and identified from several mosses and ferns. Fatty acids with a double bond in position 5, separated by more than one methylene group from other double bonds, have been found inGinkgo biloba andEquisetum. Analyses of fatty acids from numberous plants, in particular their chlorophyll containing parts, are listed according to components. The experimental part gives details on structure determination of the usual methylene-interrupted fatty acids by ozonization-hydrogenation-GLC. Alkaline isomerization combined with these procedures was applied to determine the unusual double bond structures. The method permits positional identification of an internal double bond.

TL;DR: The radioactivity in the carboxyl groups of 4,7,10,13,16,19-docosahexaenoic and 5,8,11,14,17-eicosapentaenoic acids corresponded closely to an even distribution of 4 C in the chain, however, radioactivity at least 75% of this acid must have been reconstituted from a C 20 chain.

TL;DR: Lipid classes from four species of mosses, Mnium cuspidatum, and Mnium medium from Minnesota, and Hylocomium splendens and Pleurozium schreberi from Alaska, were analyzed and monogalactosyldiacylglycerols and phosphatidylethanol-amines were enriched in arachidonic acid and the galactolipids in eicosapentaenoic acid.

TL;DR: Results of incubations with labeled fatty acids indicated that, in S. parasitica, oleic, linoleic, (6,9,12)-linolenic and arachidonic acids are major intermediates in the pathway to eicosapentaenoic acid, andethyl-directed desaturation of (n-6) to ( n-3) acids does not occur with C18 acids but is specific for the polyunsaturated C20 chain length.
