Liquid Chromatography-Mass Spectrometry (LC-MS)-Based Analysis of Molecular Lipids in Algae Samples Using Data...

Area of Science:

• Biochemistry
• Analytical Chemistry
• Marine Biology

Background:

• Lipid analysis in algae is crucial for understanding their biological functions and potential applications.
• Existing methods may lack the throughput or sensitivity required for comprehensive algal lipid profiling.

Purpose of the Study:

• To develop and validate a high-throughput analytical method for molecular lipid analysis in algae.
• To characterize algal lipids using advanced mass spectrometry techniques.

Main Methods:

• Modified Folch extraction for sample preparation.
• Ultrahigh performance liquid chromatography-mass spectrometry (UPLC-MS) for lipid separation and detection.
• Data dependent acquisition (DDA) using a high-resolution quadrupole-time-of-flight (Q-ToF) instrument for lipid characterization.

Main Results:

• The method achieves a throughput of over 100 samples per day.
• Good repeatability was demonstrated with a relative standard deviation of <15% for spiked samples.
• Successful characterization of molecular lipids in algae was performed.

Conclusions:

• The developed UPLC-MS method is efficient, repeatable, and suitable for high-throughput molecular lipid analysis in algae.
• This method provides a valuable tool for algal research, enabling detailed lipid profiling.
