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 47533 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. 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) which reflects its position in the classification hierarchy. In addition to a classification-based retrieval of lipids, users can search LMSD using either text-based or structure-based search options.

We provide multiple options for accessing LMSD records, as outlined below.
- LIPID MAPS® Classification System — View lipids by category, or drill down to view lipids by main class, sub class.
- Keyword / ontology — Search by LM ID, name, mass, formula, category, main class, and subclass.
- Structure — Draw and search by complete structure or substructure in conjunction with optional data fields.
- Programmatic Access — Retrieve LMSD data via the command line using wget.
- Download — Download LMSD as an SDF file.
- Submit structures — Submit novel lipid structures and annotations for addition to LMSD.
