Background:

• Plasma lipoproteins are complex lipid-protein assemblies crucial for lipid transport.
• Their dynamic nature and varying composition make experimental structural analysis challenging.
• Molecular dynamics (MD) simulations provide a powerful tool to investigate lipoprotein structure and dynamics.

Purpose of the Study:

• To review the current computational studies on the lipid components of lipoproteins.
• To explore the three levels of complexity in lipoprotein structural dynamics during metabolic stages.
• To discuss the role of biomolecules in lipoprotein assembly.

Main Methods:

• Coarse-grain MD (CGMD)
• MD-simulated annealing (MDSA)

Main Results:

• MD simulations enable atomistic exploration of lipoprotein particles at different metabolic stages.
• Computational studies reveal insights into lipid-protein interactions and assembly processes.
• Comparison across studies identifies key findings and areas of controversy.

Conclusions:

• MD simulations are essential for understanding lipoprotein structure, dynamics, and biological assembly.
• This review highlights the current status and future directions of computational lipoprotein research.
• Further research is needed to address existing controversies and refine simulation methodologies.
