A particularly widespread example are lipid droplets, which are spherical droplets composed of lipids and proteins that are used in both prokaryotes and eukaryotes as a way of storing lipids such as fatty acids and sterols.
Lipid droplets, which are spherical compartments filled with lipids such as fatty acids and sterols, are found in both prokaryotic and eukaryotic cells. They serve as a storage mechanism for these lipids.
