Databases

The LIPID MAPS® Structure Database (LMSD) is a relational database encompassing structures and annotations of biologically relevant lipids. As of today, LMSD contains 50,547 unique lipid structures, making it the largest public lipid-only database in the world.

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.

The LIPID MAPS® Computationally-generated Bulk Lipids (COMP_DB) is a virtual database composed of major classes of lipid species, generated from a list of commonly occurring acyl/alkyl chains. These bulk lipid species indicate the number of carbons and number of double bond equivalents, but not chain positions or double bond regiochemistry and geometry.

The LIPID MAPS® In-Silico Structure Database (LMISSD) was developed as a relational database generated by computational expansion of headgroups and chains for a large number of commonly occurring lipid classes. LMISSD 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.

The LIPID MAPS® Lipidomic Ion Mobility Database (Ion Mobility) was developed in collaboration with the McLean research group at Vanderbilt University, Nashville, TN who have generated a repository (The Unified Compendium) of more than 3,800 experimentally acquired CCS values obtained from traceable molecular standards and measured with drift tube-mass spectrometers.

The LIPID MAPS® Partial Spectra Database (Partial Spectra DB) is a specialized spectral database focused on lipids that are underrepresented in conventional lipidomics research because they are only partially structurally annotated.

The LIPID MAPS® Standards Spectra Database (Standards Spectra DB) offers high-quality reference spectra for lipidomics research, supporting accurate lipid identification via mass spectrometry.

The LIPID MAPS® Oxidized Phospholipid Database (Oxidized Phospholipid DB) is a virtual database composed of major classes of oxidized lipid species generated from a list of commonly occurring acyl/alkyl chains. Chain positions and double bond regiochemistry and geometry are not specified.

The LIPID MAPS® Shorthand Database (Shorthand DB) offers high-quality stable identifiers for lipids described at lower levels of resolution than the full-structure level contained within LMSD.
