How do lipids store energy?

What are lipid droplets?

Lipid droplets (LDs) are energy storage organelles composed of neutral lipids, such as triacylglycerol (TG) and sterol esters, surrounded by a phospholipid (PL) monolayer. Their central role in metabolism, complex life cycle, and unique lipid monolayer surface have garnered great attention over the last decade.

Where are lipids stored in a cell?

These neutral lipids are stored in the core of CLDs and emulsified in the cell cytosol by a phospholipid (PL) monolayer coat and associated proteins , . Generally, CLDs form in the presence of excess cellular lipid and are broken down when lipid substrate is needed, helping to control cellular FA levels and protect from lipotoxicity.

What is a phospholipid monolayer surrounded by lipid droplets?

The phospholipid (PL) monolayer surrounding lipid droplets (LDs) is a distinguishing feature from other organelles, which are generally surrounded by PL bilayers.
