LMSD: LIPID MAPS structure database

TLDR

The LIPID MAPS Structure Database (LMSD) is a publicly available relational database that stores biologically relevant lipid structures and annotations, all drawn consistently. LMSD compiles lipid structures from core laboratories, experimental identifications, computational generation, and curated public sources, and offers classification‑based, text‑based, and structure‑based search capabilities—including field‑specific queries and substructure or exact‑match options. Search results provide lipid structures, annotations, and links to external databases.

Abstract

The LIPID MAPS Structure Database (LMSD) is a relational database encompassing structures and annotations of biologically relevant lipids. Structures of lipids in the database come from four sources: (i) LIPID MAPS Consortium's core laboratories and partners; (ii) lipids identified by LIPID MAPS experiments; (iii) computationally generated structures for appropriate lipid classes; (iv) biologically relevant lipids manually curated from LIPID BANK, LIPIDAT and other public sources. All the lipid structures in LMSD are drawn in a consistent fashion. In addition to a classification-based retrieval of lipids, users can search LMSD using either text-based or structure-based search options. The text-based search implementation supports data retrieval by any combination of these data fields: LIPID MAPS ID, systematic or common name, mass, formula, category, main class, and subclass data fields. The structure-based search, in conjunction with optional data fields, provides the capability to perform a substructure search or exact match for the structure drawn by the user. Search results, in addition to structure and annotations, also include relevant links to external databases. The LMSD is publicly available at Author Webpage
