LIPID MAPS® Structure Database (LMSD)

The LIPID MAPS® Structure Database (LMSD) is a relational database encompassing structures and annotations of biologically relevant lipids. As of today, LMSD contains 48691 unique lipid structures, making it the largest public lipid-only database in the world.

Structures of lipids in the database come from several sources: (i) LIPID MAPS® Consortium's core laboratories and partners; (ii) lipids identified by LIPID MAPS® experiments; (iii) biologically relevant lipids manually curated from LIPID BANK, LIPIDAT, Lipid Library, Cyberlipids, ChEBI and other public sources; (iv) novel lipids submitted to peer-reviewed journals; (v) computationally generated structures for appropriate classes.

All the lipid structures in LMSD adhere to the structure drawing rules proposed by the LIPID MAPS® consortium and are curated according to our protocols. All lipids in the LMSD have been classified using the LIPID MAPS® Lipid Classification System. Each lipid structure has been assigned a LIPID MAPS® ID (LM_ID). In addition to a classification-based retrieval of lipids, users can search LMSD using either text-based or structure-based search options.
