38

Returns the list of isomeric subspecies that contain the same fatty acid component(s) at the same position(s) as a user-defined lipid, but limits the output to published lipids linked to a PMID. Output should include the corresponding SwissLipids ID(s) and name(s) and the PMID(s) for each. Extends ex:36 Output should include the corresponding SwissLipids ID(s) and name(s).
