What is the lipid droplet used for in the cell?
['Eukaryotic cells store excess fatty acids as neutral lipids, predominantly triacylglycerols and sterol esters, in organelles termed lipid droplets (LDs) that bulge out from the endoplasmic reticulum. ', 'Lipid droplets (LD) are spherical cellular inclusion devoted to lipids storage.', 'Cells store fatty acids (FAs) as triacylglycerol and package them into cytoplasmic lipid droplets (LDs). ', 'Lipid droplets are found in all cell types', 'Lipid droplets (LDs) are ubiquitous and physiologically active organelles regulating storage and mobilization of lipids in response to metabolic demands. ', 'Lipids accumulate in spherical cellular inclusions called lipid droplets (LDs) whose sizes range from fraction to one hundred of micrometers in adipocytes.']
