The LIPID MAPS Structure Database (LMSD) is a relational database encompassing structures and annotations of biologically relevant lipids. As of 12/13/2018, LMSD contains 43307 unique lipid structures, making it the largest public lipid-only database in the world.More about LMSD | Classification-based search | Text/ontology-based search | Structure-based search | Programmatic Access | Download
The LIPID MAPS Gene/Proteome Database (LMPD) is comprised of lipid-related genes and proteins; LMPD contains data for over 8,500 genes and over 12,500 proteins from Homo sapiens, Mus musculus, Rattus norvegicus, Saccharomyces cerevisiae, Caenorhabditis elegans, Escherichia coli, Macaca mulata, Drosophila melanogaster, Arabidopsis thaliana and Danio rerio.Search LMPD by keyword or database ID | Browse LMPD by Gene Ontology (GO) annotations | Download

The LIPID MAPS In-Silico Structure Database (LMISSD) is a relational database generated by computational expansion of headgroups and chains for a large number of commonly occurring lipid classes. It has been designed from an analytical chemistry perspective and a hierarchy of sum composition, chain composition and exact structures may be browsed for the various lipid classes. Reperesented categories are glycerolipids (MG, DG, TG, MGDG, DGDG, SQDG), glycerophospholipids (PC, PE, PS, PG, PI, PA, PGP, PIP(n), CL) and sphingolipids (Cer, SM, CerP, PE-Cer, PI-Cer, GlcCer, GalCer, LacCer). There are also a number of computationally generated fatty acyls (prostanes, furans) and sphingolipids (glycosphingolipids) that have been imported from LMSD. LMISSD currently has over 1.1 million structures (~ 25,000 of which overlap with LMSD). All entries have a LIPID MAPS ID, molfile, SMILES, InChIKey, exact mass, formula, systematic name and a set of abbreviations for sum composition, chain composition and exact structure.
RefMet: A Reference list of Metabolite names
RefMet provides a standardized reference nomenclature for both discrete metabolite structures and metabolite species identified by spectroscopic techniques in metabolomics experiments — an essential prerequisite for the ability to compare and contrast metabolite data across different experiments and studies. To this end, a list of 42,000 names from a set of over 200 MS and NMR studies on the Metabolomics Workbench has been used as a starting point to generate a highly curated analytical chemistry-centric list of common names for metabolite structures and isobaric species.
