Which databases are used for lipids annotation in MetaboAnalyst v5.0?

The lipids have been obtained from RefMet and LIPID MAPS.

Compared to metabolites, pathways or functional annotation of lipids are much less. In MetaboAnalyst (Enrichment Analysis module), lipids are mainly annotated based on their structures. Please choose these libraries for lipidomics data (see the fig below)

We also recommend the LION web application for lipidomics data analysis
