Update of the LIPID MAPS comprehensive classification system for lipids

Area of Science:

• Biochemistry
• Lipidomics
• Chemical Biology

Background:

• The International Lipid Classification and Nomenclature Committee established a comprehensive lipid classification system in 2005.
• This system, sponsored by the LIPID MAPS Consortium, is based on chemical and biochemical principles and utilizes a flexible ontology.
• It has been widely adopted internationally and is compatible with modern databasing and informatics.

Purpose of the Study:

• To review and present updated details of the comprehensive lipid classification system.
• To incorporate revisions based on global lipid researcher feedback.
• To provide updated nomenclature and structure-drawing recommendations for lipids.

Main Methods:

• Review of the existing comprehensive lipid classification system.
• Incorporation of revisions to better represent diverse lipid structures.
• Development of updated nomenclature and structure-drawing guidelines.

Main Results:

• A revised and updated comprehensive classification system for lipids is presented.
• The system now more fully represents lipid structures from a wider variety of sources.
• Additional levels of detail have been incorporated as necessary.

Conclusions:

• The updated lipid classification system provides a more comprehensive and detailed framework for lipid research.
• Revisions ensure continued compatibility with databasing and informatics needs.
• The enhanced system supports global lipid research across various scientific fields.
