LIPID MAPS® In-Silico Structure Database (LMISSD)

Hierarchy of lipid structures from analytical chemistry perspective

Description

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.
