Lipidomics is a relatively new field under the heading of systems biology. Due to its infancy, the field suffers from significant ‘growing pains’, one of which is the lack of bioinformatic analytic resources that other “-omics” fields enjoy. Here, I describe the creation and validation of the glycerophospholipid identification program VaLID. Using an in silico approach, we generated a comprehensive database containing all of the glycerophospholipids within multiple sub-classes: those containing chains of 0 to 30 carbons with up to 6 unsaturations and various linkages. Using Java, I created a web- based computer interface with a search engine and a visualization tool to access this database. In comparing results to current programs, I found that VaLID consistently contained more identity predictions than did the current gold standard LipidMAPS. Results from several tests with real datasets confirm that VaLID is more than capable as a phospholipid identification tool for use in lipidomics.
