Examples

  1. Select the SwissLipids categories and their labels.
  2. For a given (list of) lipid Species identifier(s) (e.g. SWISSLIPID:000056420 (Phosphatidylcholine (20:2)) SWISSLIPID:000308470 (Triacylglycerol (64:6))), return a list of the corresponding Molecular subspecies (if any), Structural subspecies (if any), and Isomeric subspecies. The query should return the lipid recommended names as well as identifiers. The list should be sorted by level in the hierarchy (Isomeric subspecies last). Future versions of this query should be generic enough to work from any start point (Species, Molecular subspecies, Structural subspecies). Recapitulates the “browse lipid analytes” function of the website (in batch).
  3. For a given (list of) lipid Species identifiers (e.g. SWISSLIPID:000056493, Phosphatidylcholine (32:0)), return a list of the corresponding Molecular subspecies (if any), Structural subspecies (if any), and Isomeric subspecies (if any) which are associated with at least one citation (PMID: PubMed id). The query should return the lipid identifiers (?id), recommended names (?name), and PMIDs (?citation). Future versions of this query should be generic enough to work from any start point (Species, Molecular subspecies, Structural subspecies).
  4. 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).
  5. For a given lipid (SWISSLIPID:000399814, Ceramide), return a list of all corresponding reactions (Rhea IDs and equation). This query does consider the hierarchy: it looks for reactions involving the specified lipid and/or its more specific forms.
  6. For a given lipid (SWISSLIPID:000399814, Ceramide), return a list of all corresponding reactions (Rhea IDs and equation), as well as their enzymes as annotated in UniProtKB/Swiss-Prot) enzymes themselves (ID and protein name). This query does not consider the hierarchy: it looks for reactions and enzymes only for the specified lipid.
  7. For a given list of lipid Species, return a list of the corresponding Isomeric subspecies for that particular lipid that are linked to an enzyme as annotated in UniProtKB (UniProt AC and recommended name). This question would allow a user with (a list of) very high level MS identifications to immediately narrow them to the most likely potential lipid structures and protein targets as in this example: SWISSLIPID:000056871 / PC(O-36:4) (target species of interest) -> SWISSLIPID:000028143 / PC(O-16:0/20:4(5Z,8Z,11Z,14Z)) -> LPCAT4, PLA2G4A, PLA2G4C, PLA2G4F (target proteins)
  8. Retrieve mapping between SwissLipids lipid identifiers and their corresponding LIPID MAPS identifiers. Output should include SwissLipids identifier and name plus the LIPID MAPS identifier.
  9. For a given list of LIPID MAPS identifiers return the list of corresponding SwissLipids identifiers. Output should include SwissLipids identifier and name plus the LIPID MAPS identifier. This query considers only the cross references in the SwissLipids entry – it does not attempt to query other levels to find links between parents or children. Recapitulates one ID mapping function on the website
  10. Retrieve mapping between SwissLipids lipid identifiers and their corresponding HMDB identifiers. Output should include SwissLipids identifier and name plus the HMDB identifier.
  11. For a given list of HMDB identifiers return the list of corresponding SwissLipids identifiers. Output should include SwissLipids identifier and name plus the HMDB identifier. This query considers only the cross references in the SwissLipids entry – it does not attempt to query other levels to find links between parents or children. Recapitulates one ID mapping function on the website.
  12. Retrieve mapping between SwissLipids lipid identifiers and their corresponding ChEBI identifiers. Output should include SwissLipids identifier and name plus the ChEBI identifier.
  13. For a given list of ChEBI identifiers return the list of corresponding SwissLipids identifiers. Output should include SwissLipids identifier and name plus the HMDB identifier. This query considers only the cross references in the SwissLipids entry – it does not attempt to query other levels to find links between parents or children. Recapitulates one ID mapping function on the website.
  14. For a given list of LIPID MAPS identifiers return the list of corresponding ChEBI IDs. Output should include LIPID MAPS ID, the corresponding SwissLipids ID and name, plus the ChEBI ID. This query first identifies SwissLipids identifiers for a given list of HMDB identifiers. It then retrieves all children and from them the required LIPID MAPS identifiers. extends ex:9
  15. For a given list of LipidX lipid identifiers return the list of published Isomeric subspecies. Output should include the LipidX ID and the corresponding SwissLipids ID(s) and name(s) plus PubMed ID(s). This query first identifies SwissLipids identifiers for a given list of LipidX identifiers. It then retrieves the corresponding Isomeric subspecies that are linked to at least one publication, and the corresponding PMIDs. extends ex:15
