For a given (list of) lipid classes (e.g. SWISSLIPID:000399814 (Ceramide) SWISSLIPID:000000007 (Sphingomyelin (iso-d17:1(4E))), return a list of the corresponding Isomeric subspecies. The query should return the lipid recommended names (?name) as well as identifiers (?id). Recapitulates the “browse lipid classes” function of the website (in batch).
