The lipid maps initiative in lipidomics

Area of Science:

• Lipidomics
• Systems Biology
• Biochemistry

Background:

• Lipidomics is an emerging field facing significant obstacles to becoming a comprehensive systems biology approach.
• The Lipid Metabolites and Pathways Strategy (LIPID MAPS) initiative was established to address these challenges.
• Existing lipid classification and nomenclature systems presented limitations for broad-scale exploration.

Purpose of the Study:

• To introduce challenges and solutions in the field of lipidomics.
• To present the development and adoption of a new comprehensive lipid classification system and nomenclature.
• To discuss the role of mass spectrometry in advancing lipidomics research.

Main Methods:

• Development of a comprehensive lipid classification system by the International Lipids Classification and Nomenclature Committee (ILCNC) in collaboration with LIPID MAPS.
• Adoption and utilization of mass spectrometry (MS) as the primary instrumental platform for lipidomics.
• Review of existing literature and ongoing initiatives within the LIPID MAPS framework.

Main Results:

• A new, comprehensive classification system for lipids has been established, including recommended nomenclature and structural representations.
• Mass spectrometry has been identified and adopted as a versatile platform for quantifying known lipid species and discovering novel lipids.
• The LIPID MAPS initiative has developed crucial infrastructure and techniques to overcome hurdles in lipidomics.

Conclusions:

• The implemented lipid classification system and nomenclature provide a standardized framework for lipidomics research.
• Mass spectrometry offers powerful capabilities for both quantitative and qualitative lipid analysis, essential for systems biology.
• LIPID MAPS is instrumental in advancing lipidomics as a robust systems biology discipline.
