The LIPID MAPS® Structure Database (LMSD) is a relational database encompassing structures and annotations of biologically relevant lipids. As of today, LMSD contains 46834 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® 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. 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.
COMP_DB is a virtual database composed of major classes of lipid species, generated from a list of commonly occuring acyl/alkyl chains. These \"Bulk\" lipid species indicate the number of carbons and number of double bonds, but not chain positions or double bond regiochemistry and geometry. Note that many of the lipids in COMP_DB may not be relevant to mammalian samples.
The Lipidomic Ion Mobility database was developed in collaboration with the McLean research group at Vanderbilt University, Nashville, TN who have generated a repository (The Unified Compendium) of > 3800 experimentally acquired CCS values obtained from traceable molecular standards and measured with drift tube-mass spectrometers.
